This is a spoiler.
Well, the reason why they broke up is because of MC's sister. She died. People thought she commited suicide but for MC it was not like someone was trying to threaten her. Him and mc started investigating the case together but somehow, the investigation got too deep and the death of his sister wasn't simple. While investigating, male lead got threaten that what happened to the MC's sister will happen to MC if he doesn't stop investigating so male lead decided to betray MC and left him. That made MC hate him. He could also know if the person lies. So whenever the male lead lies he knows.

OMG I KNEW IT! oh how i hope that the ml never actually genuinely wanted to leave the mc, like he was the one who liked the mc first too and initiate wanting to be with him! AHHH i can’t wait till the mc figures it out cuz i feel so bad for him rn, they still love each other ughhh pains me to see them not together ヽ(`Д´)ノ
He never did. But he lied that he wanted to leave MC. MC asked him why did he leave him. There was a scene that MC got to change into female clothes and he look so good! Just like his sister and the male lead caught the sight of him. He got mad at MC because he's there wearing something like that. xD like he got jealous when MC kissed someone on the cheek.
i’m just trying to understand what tf is the seme doing- like WHY DID they broke up?! they obviously were lovey dovey before and the seme lovedddd the uke, but what made him leave?!? like i just feel bad tbh,, im literally gaslighting myself believing he left cuz of some dangerous mission that could risk the ukes health or smt… cuz nah what the hell… but rip i guess it’s been dropped? so we’ll never know
