MC and ML was friend in high school (If I remembered correctly... (っ- ‸ - ς)) They both had past relationship before getting together. ML had two girlfriends in the past, in high school and in college. ML was someone that devoted to relationship, he even reached stage where he thinking about married and form a family with one of the girlfriend back then. But in the end, her mindset didn't match with ML (she literally said that the way ML treated her was like how an old couple in 60 or 70 years old getting along lol.·°՞ (̑ ᗜ ̑) ՞°·), so they broke up. ML was quite rigid in relationship lmao, that's why he needed MC as someone that could guide and understand how he feeling.

On other hand, MC had relationship with Zhou Muyao (Xiao Hei), family of ML. What makes MC ended the relationship was that Muyao having emotional infidelity with one of his friend. I think that's the last straw of the relationship, other than that is their personality isn't compatible. Zhou Muyao used being center of attention between his friends, so he always expect other to cater him without minding what MC's need in relationship. MC's sense of self being blurred because that ex selfishness, especially friendships he had with others.

ML doesn't realize the concept of homosexuality until he knew MC dating Zhou Muyao. It's really fascinating how ML gradually noticed the shifting of their relationship after reunited again. The first thought MC had when ML confessed was guilt because he seems dragging a 'normal' person into wrong way QAQ ML is so thoughtful that he gave time for MC to sort out his thought before accepting his confession, with tacit understanding not pressuring MC

The story was written thoughtfully, especially the character. I LOVE MC's MOM, she's a single mother that raised MC with much love. She's outgoing and open minded, accepted her son's orientation right away, and understanding her son's personality really well. Like there's scene where's Zhou Muyao helping MC's mom with subtle thought to make her persuaded MC to getting back together with him. I really want to knock some sense into MC's ex, but MC mom's already did it first lol. That ex acted like typical chasing wife's behavior with pestering MC and acted he's the only one who's hurt after their breakup. MC's mom gently pointed how MC constantly drained in their relationship, how that ex acted immature and their personality doesn't match. Really, in the end that Zhou Muyao was really a brat, especially after he knew MC and ML are together.
