Whenever I need titles I search for some rare words that have beautiful meanings that no one really knows about. But here's what I thought matched in the case of Jonghyun. (Idk it just reminded me if his character)

Idk if the link worked but it's:

Sarang - (v) the feeling of wanting to be with someone until death
(This is a Korean word, we know that but not a lot of people actually know the actual meaning in my opinion)

But there's also this one

Alexithymia - (n) the inability to express your feelings
(Jonghyun's character)

Or maybe 'Not too Late' for yenno the fluffy ending if you're gonna do that

man idek if I helped
