I am having problems getting an ending with Yoshihiko. I tried to max it out for all of them at the same time to test the endings for each but I can't seem to trigger the ending no matter how many times I lose the relationship is stuck at level 9 and he just keeps buying her but not buying tickets out for both of them. What do I do?
Edit: It seems the only way to trigger the ending is to seemingly confess to each of the guys? I don't really get that but what else can I assume with a heart icon on that option, right? Which makes them decide to leave, and take Alisa with them, if you lose to them afterwards.
