title name?

(BL) Where the uke is an author and he likes toxic seme (kinda), then the seme is a two-faced person, who pretends to be a good person but is actually a jerk. The uke then use him as a reference for his book. The seme is actually a good person with a tragic past, his mom abandoned him, then his auntie adopted him. The auntie used him to get her father's approval. Uke and seme dated, then seme found out that the uke is using him (ps: he's tired of people using him) which is why he got angry. It was a misunderstanding, and uke have a hard time understanding emotions and such, but he actually loves the seme.
