I don't think some people get the backstory. It's not a "trauma" or a "boo hoo" story. It's showing a pattern on the ML's (lack of) feelings in a disorderly way. No sense of caution, continous impulsiveness out of curiosity (not even seeking excitement by himself), no lingering attachments, no bonding with anyone or anything. It also shows how he does not lie, but just avoids confrontation in things he deems are stupid but know will tick people off (like saying his exes are just "people he used to know"). However, he is also very comitted to what he gets into, and that's why he may look like the whole boyfriends package superficially, but he's never felt anything beyond "interest" so he does pretend to treat his partner beyond the starting stage of a relationship where people are just "meeting" each other instead of "loving" each other. That's why no one can stand being by his side: he is true to himself so he doesn't leave because he is comfortable in that stage, while his partner wants to go forward. And accepting to get with anyone that calls out to him means he's ran through and is used to living that with ALL his partners through ALL his life.
He's anti-social and didn't even realize how this time was different from others until it was too late. In other words, the backstory is not trying to say "feel bad for me my live has been too easy", it says "holy shit I fumbled for assuming it was the same as always, now what can I do?"

As a marketeer, I would've quitted inmediately lol It's already a fucking big red flag to have such massive creative differences on the mere values of a marketing campaign (many marketing teams literally break up due to this), but now this dude on top of that has been mocking my work for ages which has trashed my reputation and the trust on my work online and virally, and joined the project knowing who I was and didn't tell me shit until we were already involved. Nah fuck that. ML is lucky that MC is too much of a good boy to abandon the project.
Maybe I'm having a bad day but I think Imma drop just for this. Too personal to my real life to turn off my brain.

Hopefully he has the most golden chasing arc because he thinks like a total psycho King. Poor Luce.

This is exactly what I'm talking about, the novel shows that Ail can't survive without Luce, but he still has a very haughty approach when taking back Luce.
Like you've had no problem being verbal and physical with the torture you inflicted on Luce, but are having trouble expressing how important he is to you? He is not verbal about being undeniably in love with Luce, or sorry or regretful. Like after everything he's done, he should've been SOBBING!! On his knees!!

Yah he should have but he taken many arrows for luce to protect him even if it means to kill himself in process that didn't matter to him he just wanted luce breathing and living he cannot live without luce that he would even kill himself, although both of them are same if one day ail chose someone else he would kill ail and then himself he is possesive of ail too
Brother just punch him in the face. Yes, you'll have to justify when the team finds out, so fucking what? When you explain this toilet paper face not only didn't give you space after you crearly told him off politely, but then sexually assaulted you and literally held you so you couldn't escape otherwise, who do you think is gonna blame you? And if the little bitch then does one of his ambiguous stupid tweets or whatever and makes the fans turn on you, fucking go at it and say how he sexually assaulted you publicly. Risky but he's the ones that always dors this shit publicly so guve him a taste of his own medicine.
I just fucking hate the ML, if he doesn't fucking beg for forgiveness I'll just drop.
