Ik this is BL story but on a wide real life spectrum this type of emotions and everything portrayed in the story actually happens a lot between couples and it is sad to them .... miced emotions , overwhelmed one that can't be controlled, sadness yet happiness.. it's the type of love that is called sad love ( it's just a type of love between couples that there's always some lingering sadness in it yet they still are working their way through it ) .

Spoilers?

As far as i remember
