I. Three Must-Do Things in First 3 Minutes

After the opening training scene, don't wander around. Go outside immediately and pick up money. Once you have cash, buy the Light Stream Fishing Rod and head straight to the fishing spot. You need to use Cheat Engine here—don't hesitate. This game moves fast, and manual fishing will exhaust you. After catching fish, modify the quantity directly. Remember this iron rule: always manual save before every strength/technique training session and before every intimate scene. This game has no auto-save; one mistake means reloading until you rage quit.

II. Complete Heroine Profiles + Exact Timetable

Five heroines, each with unique traits. Mayuko Hasegawa: housewife attributes maxed. Ayano Matsushita: student rep. Yui Matsubara: convenience store worker, construction site target. Rika: the old man's friend's daughter, muscle girl, protein queen—her physique is too much for ordinary people. Aoi: from the Forgotten Clan, lotus-leaf-wearing river girl, outdoor play specialist.

You'll dream of new heroines before they appear—the dreams featuring Ayano and Rika are system hints. Memorize these exact spawn times:

Ayano Matsushita: Appears exactly May 17th (Wednesday)

Muscle Girl Rika: Spawns once every 5 days, fixed schedule

May 16th (Tuesday), May 21st (Sunday), May 26th (Friday), May 31st (Wednesday), June 5th (Monday), June 10th (Saturday). This timeline matches the calendar exactly. Challenges don't consume time—if you start at 9 AM, it's still 9 AM after. No more challenges appear after June 10th; miss them and they're gone forever.

Side note: that damn old man sleeps during challenges, and when the MC gets forced, he just stands there watching with a blushing face—what good are you?

III. Map System Deep Dive

Seven locations total: Construction Site, Aoyama Mountain, Apartment, Residence, Shop, Cinema, and Dojo. Traveling between any locations costs exactly 30 minutes—the system is strict. When choosing to sleep until next day 9 AM, the system rounds up partial hours. Sleep 2.5 hours? System only counts it as 30 minutes of recovery. Stingy as hell.

IV. Construction Site: Yui's Route + Mining Riches

Construction Site is Yui Matsubara's home ground. Two routes here: Yui's personal story and mining for riches.

1. Yui Story Route: The construction worker stays 8:00-19:45. You can work 3 hours or mine 5 hours. After Yui's YD value maxes, black shadows appear at the site corner from 0:00-2:00. You'll encounter them at 2:00; third encounter triggers choices. Next day at 0:00 unlocks scenes, then you can join activities at 0:00 nightly (costs 2 hours). Repeated clicking may have bugs, but won't block story progress.

2. Mining Riches Route: The game's most profitable path. You can switch drill bits mid-dig—activate all 4 drill slots and use them in order. Underground rock layers thicken every 250m; 1271m is the bottom. Digging big chests has chance for Gold Bricks and Sea King Rod. Don't dig anything before 300m; dig straight down for fastest descent. Black market dealer appears at site 20:00-02:00; sell your treasures to him.

V. Aoyama Mountain: Aoi Complete Guide

Aoyama Mountain is Aoi's territory—fishing and outdoor scenes here.

1. Fishing System: Sea King Rod from mining big chests enables full-screen fishing, slightly larger range than Dragon King Rod. Each successful fishing takes 15 minutes. Rich guy Miura enters tent to sleep at 19:00; trade fish with him by 18:45.

2. Aoi Guide: Can chat after 19:00. After several chats, bring food for Aoi to increase affection. Food order: meat bun, oden, omurice, fruit cans—don't mess up. When affection maxes, accepting Aoi's request grants item "Aoi's Love Letter". Then buy laxatives from black market. Chat once more that night, next day after 16:00 you can use laxatives (can't use earlier), then proceed. Tent entry time is 19:00-0:00; during this window you can plan cinema visits. Use laxatives then immediately go to cinema—return after movie, zero time wasted. After 3 times in one position, unlock next two positions—be patient. Trigger line is "Why is it you, why you again, of course it's you". Entering tent costs no extra time—very generous design.

VI. Apartment & Residence: Late Night Infiltration

Apartment and Residence require YD Level 4 and 5—homes of Ayano Matsushita and Mayuko Hasegawa. Can enter daytime; can visit at 16:00. No one home at 19:00, can't enter at 20:00, must wait until 1:00 AM. Process: sell videotapes and wait for the victim to enter negative state, then infiltrate at midnight. (If YD value sufficient but target hasn't bought/watched tapes, game warns don't go.) Day and night have 2 scenes each, taking 2 hours. Camera installation: Apartment has only 1 spot, daytime only. Residence allows day/night installation. Requires heroine not home; recommend visiting morning for safety.

VII. Shop & Cinema: Gifts & CG Unlock

Shop is Yui Matsubara's territory. Chat with Yui each visit; later unlock 3 CGs at cinema, then refill YD value at shop (no time cost) to trigger construction site story. Buying gifts for the 2 victims at the dojo increases affection for achievements.

Cinema hours 10:00-22:00. After 16:00 until 21:00, see heroines at entrance; ask what movie type they're watching. Whichever heroine you trained that day, you'll see her at cinema that afternoon. Arrive early to potentially watch 2 movies back-to-back for maximum efficiency.

VIII. Dojo: Training, Money & Filming Combined

Dojo is training ground for Mayuko Hasegawa and Ayano Matsushita. One judo session with heroine takes 4 hours; intimate scene takes 1 hour. Higher level judo lessons (pinning techniques) give more EXP; human partner gives more than mechanical arms. Doing it 3 times gives more YD value EXP than once. Film videos for money while you're at it—triple benefit.

IX. Ultimate Skill Training Guide

8:00-21:00, find the old man to boost skill levels—1 hour per session, price increases after several trainings. After mining Gold Bricks and trading for Golden Dolls, money won't be an issue.

1. Strength Training: 24k Gold Bricks, max 10 consecutive breaks, fixed 3280 EXP—this number never changes.

2. Technique Training: Left-click red, right-click blue. Golden Doll max 25 consecutive, 15 dolls. EXP scales with level—higher levels more cost-effective.

Can switch training items mid-training—useful if you selected wrong item to avoid wasting time.

X. Ending Choices + Achievement Farming

CRITICAL: Save on June 19th—this is the most important checkpoint. On the 20th, choose between 5 options: Housewife, Student Girl, Convenience Store Girl, Muscle Girl, or No Farewell. All endings will feature the "couldn't say goodbye to Aoi in time" scenario—don't worry, this is scripted. After clearing, reload June 19th save repeatedly to farm achievements. Be careful not to overwrite it, or you'll have no way back.
