What if there's a part of the game where you also have your energy and when it's low you need to sleep (you can sleep anytime), either couch or beside mayu on bed, then, if both of mayu's love and desire gauge were 500 or 600up, there will be an h-scene, suggested h-scene was cowgirl, cuz you're lying down, and also, a part where you can also wake her up, or where there's another h-scene (when you sleep on the couch or up to you devs), which is blowjob
Additional: what if when she is just laying down on the bed, (on her belly) laying down flat, using her phone(laying down flat) or reading a book (on her belly) each of those triggers an h-scene
Laying down flat(using her phone): triggers h-scene missionary (need 500up desire)
Laying down on her belly(reading a book or using a phone): triggers h-scene pronebone position (also need 500up desire)
This only happens during afternoon but if you don't have the requirements to trigger the h-scene, it'll be just a normal chitchat
(Just suggesting, idk if it's a great idea or nah thankyou)
We should also give mayu some chances too, hweheh ;)
