Help me find a BL

So I never read the main couples story but I did read the side story of the second couple. If I remember correctly one of them is dark blue haired while the other is a white haired. One scene I remember is where the White haired boy wanted the Dark haired to directly say “I Like You” and the Dark haired was like “Do I really need to say it for you to know I like you?” And they’re on the couch I think. Pls Pls help me find this BL I’ve been suffering for a few hours now
