What's this bl

What this bl pls, so like it's a flashback, the seme is super popular in elementary and gets candies and gifts like that but he has his eyes on uke and one day the seme bought a lollipop and decided to give it to uke and the uke ask him something along the lines "did u buy this for me" or "where did u get it" I don't remember sorry, so like the seme then lied and replied along the lines "someone gave it to me" or "it's a gift from blabla" like that, then the uke got angry (they're in elementary it's a flashback and it has a black background
