I forgot completely about the title of the manga this oneshot is in, but it's a short chapter. It's from the seme's point of view about his boyfriend who is the dark, gloomy, nerdy type. The seme is the bright and popular and stylish type and I forgot how they got together (not elaborated much).

In the story they were already living together, but the seme was upset because the uke seems so cold and uncaring when it's the uke who confessed. He considered breaking up with uke because he convinced himself seme is not really in love with uke but turns out he couldn't because he really like him after all.

Thank you

I think it's the third story in Scarlet
