Libido bonuses: Shiny lights on maps that increases your libido.
Day 1: 2nd floor top middle room, 2nd floor top left room.
Day 2: 1st floor bottom left room, 1st floor bottom right room.
Day 3: 1st floor top right room, 2nd floor bottom right room.
Day 4: 2nd floor hallway, 2nd floor bottom left room.
Ending 1: Normal Ending (Or also the virgin ending).
Talk to various NPCs around with the exclamation mark above their head to get through the whole game. Do not train because that will eventually cause you to get sleep raped. Final day just train until night, go to 2nd floor, and go to the top middle bedroom.
Ending 2: Pregnant Ending (with childbirth CG scene).
Go through any scenes where you basically get impregnated. I personally did this ending unknowingly by training every single day morning and evening, then talking to an exclamation mark NPC to end the night. I did this to finish the sleep rape scenes and the 4th scene was the impregnation. Final day is the same as ending 1, just train until night, go to 2nd floor, then go to top middle bedroom.
Ending 3: Kyngus's Virginity.
You have the option for this ending every single time on the final day. On the final day, train until night, then talk to Kyngus in front of the dining hall door on the 1st floor (to participate in the party).
Ending 4: Marriage with Yario.
Day 1, finish physical examination first, during evening go into the dining hall on 1st floor to talk to him, and he will give you a massage the next day morning. Day 2, during morning go to 2nd floor top middle room for scene. Day 3, during morning go to 2nd floor top middle room again. Day 4, during night go outside, walk to the front gate (south), and talk to Yario. Day 5, train until night, go to the front gate, and talk to Yario. I don't know if you need a certain Libido level for the ending but just get all libido bonuses just in case.
Ending 5:*do not train or masturbate at all, unless stated otherwise*
Day 1, during evening, talk to commander in his office on 1st floor bottom right (choose their love). During night, go to 2nd floor bottom right room. Day 2, during morning, go to 2nd floor bottom right room, talk to the 2 guys sitting down. During evening, go outside, walk down the stairs, and walk to the left and talk to the 2 guys sitting on the bench. During night, go outside, walk right, take a bath. Day 3, during morning, talk to commander in his office on 1st floor bottom right room. During evening, go to 2nd floor bottom right room. During night, go outside, walk right, take a bath. Day 4, during morning go to 1st floor bottom right room. During evening go to 2nd floor top left room. During night, go to 2nd floor bottom right room. Day 5, during morning go to 2nd floor top middle room. During evening, go outside and train. After this you should have sex-crazed level of libido, enabling the 5th ending. During night, go to 2nd floor top left room.
P.S.: If you're trying to get all the scenes for sleep rape, just focus an entire run on that (which also gives you ending 2). Train morning and evening, then find an interaction to end the night.
