it would be nice to have that for people who missed out on the heart or skipped it by accident but I don't know how Hyao would add that. the point of it is that you DON'T sleep with Logan because he's not ready, but if you complete his storyline, he is. meaning Hyao would need to either rewrite it or just let it be a weird thing in progression.
however Hyao will be adding other ways to get hearts with characters so you can still get 3 hearts at minimum since the max we know about hearts is four, meaning Logan is going to get one more guaranteed heart event. maybe we can get more hearts later and that will add to the minimum but we don't know right now lol.
