okay, let me share my thoughts while i translated this.
1) taejun starts off by apologising for being sensitive due to his work. wonyoung says that's not what he needs an apology for, as that has never bothered him.
2) wonyoung says what bothered him was how he felt like he was useless (remember, wonyoung feels this way cuz of how taejun never let him in the studio, and cuz he was comparing himself to the ex)
3) taejun responds by telling him that his ex had his own faults too. yes, they could relate to each other professionally, but that's it. he wasn't a suitable life partner.
4) he explains to wonyoung how he has made his life so much better. he tells him how he no longer has insomnia and is eating proper meals thanks to him. he literally says 'you changed the way i see life'. that's him saying that wonyoung isn't useless at all, but has instead helped him the most out of everyone.
5) taejun doesn't need to apologise about the studio thing, cuz he has a very valid explanation for it. yes, he could have worded it better when he rejected wonyoung in the last chapter, but he does apologise for it.
i think that's it. i mean, obviously you're free to form ur own opinion to it, totally fine. i think u might feel that way cuz the whole thing was resolved in half a chapter, when the buildup took 2 chapters. the way i see it, taejun doesn't need to grovel to ask for forgiveness. maybe its cuz i relate to him, but i dont think what he did was *that* bad. they just talked it out like adults!

Maybe it felt lacking in the part because us readers feels differently than MC. We as readers most took offense at the part how many times MC was brushed off at the studio thing and the neglect after that, meanwhile MC's took offense at the feeling he can't support ML.
And as the TL already said, ML already apologizes what MC needs for an apology

yes! i also believe that after reading so many stories where a conflict is resolved with a long chasing arc followed by an emotional reconciliation, the way wonyoung and taejun just sat down and talked things out healthily in one go might've seemed a little underwhelming. i think that's what makes this story great though, it's more grounded in reality than the others.
I quite don't like how the seme apologize. I don't know something about it doesn't sit well with me.
