when you are around your mama, you can go with her some place, there are some H-scene you and her, everytime you are spending time with her will consume stamina, when you leave her, this will fine if no other male appear on map,if they are appearing, do not leave your mom alone or else she will get NTR,so far, there is a fat ugly old pig near your home, if he appeared, do not stick with your mom, she will get NTR anyway, you can't stop that pig for sure, idk if this is a bug or not, when your pop come home, you can freely go anywhere you want,watch your stamina bar, 1 shower scene with moma can consume 1/5 it, ( early game very dangerous, late game when your level high enough, your bar also increase), if your bar low, you can go alone to some place for a rest, early game when your papa come home, at night you go with them to the restaurant, but later, you will go to hot spring at night, after long chat, there will be 2 choice, 1st one will stick with your mama to avoid NTR scene ( remember, a shrimp like men will always at the hot spring ), 2nd option will take bath with your kohai - o have sex with her, also mean your mom with be rape by a shrimp . Your kohai sometime appear on map at noon, if you go there, you will meet her changing cloths, do it many time and 1 day you get invite to her room, there are 2 choice, that's what i'm stuck at to get her good ending i think, at night, japanese tea shop , where your kohai is working, you will get a blowjob scene, have sex with kohai inscrease stamina <<<< lol, but also you miss your mama shower scenes, sometime when you go with your mama to the pool, you will meet a pig, sticking around your kohai, there is an option to see they have sex, late night, scenes having sex with your mom, early game only blowjob, later, each scene consume 1 condom, if your condom run out, buy it at shopping district when you go alone, still can't find the way for good ending heartful maman mc kohai)
