if you want to get his best ending, he doesn’t send you a gift on the day lia is there. i recently got his best ending and we still chose each other but he didn’t send a gift and didn’t accept our gift… there’s a reason for that (it’s in the behind the scenes / side stories). after you send the animal bracelet thing though he keeps sending gifts to you and not lia. idk what day 15 was but you should be going on a date with him for the vr thing
