1. ML not even caring for MC over his white moonlight (repeatedly). What pissed me off the most was the drinking incident in 1st chap and the bus accident one (which leads to the break-up).

2. Apparently the ML and MC hits each other (?) whenever they fight

3. This is the one that pissed me off the most; ML saying that MC was annoying to his white moonlight right after their 'wedding photo' was taken.

4. MC is said to be controlling, but he only tells ML to quit smoking and stop hanging out with bad friends. Since MC doesn't have a private life for ML to control we can't even see if ML would've been controlling.

5. ML still liking his white moonlight even after 3 years of dating MC. This counts as emotinal cheating for me. He also says weird stuff like the white moonlight is an unattainable dream that he can only daydream about but MC is the one he will ultimately return to, which is such a scummy thing to think like tf?

6. The whole being considerate to white moonlight despite MC being uncomfortable with it and then brushing MC's feelings aside.

7. When ML comes back for MC he claims to not understand things, that he is slow, and explains that to be the reason for his behaviours. He claims to like MC and not the white moonlight (This feels like either the author forgot the what happened or the ML was gaslighting the MC)

8. ML also compares MC dating someone else (AFTER THEY BROKE UP) to him having feelings for white moonlight (WHILE THEY WERE DATING) and claims that the hurt he felt was the same as the hurt MC felt throughout their relationship and therefore its even (?). [This part made me so mad. ML sounded so manipulative.

and even the ML is related to them like mmmm

The main source of the misunderstanding can be partially put on the MC's head as well. MC has his own pride and arrogance and unwillingness to confront the ML about his own doubts. So TL;DR although the ML is a bit scum, it wasn't entirely his fault and later on makes up for it.

the way the author wrote the second ML's actions and outcome was too arbitrary.

Although the author was convincing for having the ML get a second chance, it was super unrealistic that the MC dated the 2nd ML for like 2 years and they never slept together. This immediately brought to mind the obsession asian culture has with purity and how the MC can only have relations with the ML he ends up with. Especially with the argument and the accusation that the ML threw at the MC for having another boyfriend after they broke up... Left a bad taste in my mouth. Asian culture toxic af.

And it's pretty obvious that if the MC had actually given the 2nd ML a real chance, he would have changed enough to really treasure their relationship (which had instead remained lukewarm for 2 years because the MC never really gave in). Pretty clearly, the second ML was too strong/good so the author chose a lot of arbitrary plot points in order to make the 2nd ML appear worse than the ML, regardless of logic.

Meh.

Like how he could be so over controlling to ML. Idk, maybe it was good but I felt that in relationship you have to be equal. At later part, he even wondered if he truly loves ML or that he just enjoys the conquest, which is kinda sad at one point.

Also, you can be mad at me when saying this but the MC clearly knows that ML has a white moonlight, albeit the latter is a scum. He even suggested the relationship as trial at the first place, so he surely knows what he's getting himself into. At some point, he's the one bringing this to both of them.

ML itself is not without flaw. He was childish before, he didn't know what to do with his life, like a kid who just wanted to brag etc and with bad communication that ended up being misunderstood by MC even losing Tang Yi's trust. At another point, I couldn't blame him so I think he was redeemable more than the MC in my eyes.

At least after 2-year of separation, he became more mature in a way. It was right for his jealousy and he didn't even force himself too much. It was the right amount (to me at least). MC, on the other hand, was still the same, hot-headed and immature. MC always thinks more of himself. Everytime I read how he was always angry at ML later, I was like, "DUDE, you ruined someone's life too. I mean, you forced him to do things that he probably didn't like before. STOP BEING SO DRAMATIC AND ANGRY ALL THE TIME!"

Later on, at least he finally realized that he was the one pushing the ML at the 'wrong path' when he introduced the designer job? I cried when I read the ML was happy that he could score a project and wanted to shout out at MC that he could finally do it. See how suppressed he was under MC?

I first rooted for 2nd ML but then again I thought, nah, MC didn't deserve 2nd ML. What Zhou Hou did was not entirely bad at some point in his business point of view, which is why I think they didn't deserve each other and MC should just go back to ML so he won't hurt others more.
