Also do you mean "serious/sensitive topics discussed later" meaning there will be "protagonist receives aftercare. Will there be jealousy and protective behaviors from the other characters toward the protagonist? I’d love to see some scenarios where the protagonist gets hurt, and the other characters find them in that state getting fixed and healed by them.
Could the protagonist potentially go on a solo holiday that highlights their separation anxiety, finding you have disappeared? It would be interesting if the protagonist experiences nightmares and needs comforting, possibly leading to a scene where you pick one of the characters as they sleep in their bed and you go to their dorm room and bedroom without them knowing you get in their bed with them and sleep with them, which they would need to discuss the next day.
Also, it could be engaging if the protagonist can develop relationships with each character based on the chosen route, including the option to start dating them. If that’s too much for the current storyline, perhaps it could be explored in a future update." and maybe a little bit on the protagonist having a bit of a suicidal thought episode? Or would that be a secret?
