In his defense:
1. He just had a fucking baby, ever had of hormones? If you haven't, they can cause mood swings, even after the baby is born.
2. He just came back from a drinking party and is fucking drunk. He wws trying to feed the baby, which he shouldn't have since the baby was asleep. But him throwing a fit,while drunk and hormonal, is a completely normal thing. A lot of new mothers don't feel loved after giving birth because their partner is more focused on the baby. This can lead to post natal depression too.
3. He was and is spoiled. This was made clear from chapter 1. He was doted on and spoiled by his father, brother ,the nanny and later on KJ too after they started dating. Expecting someone to "magically" change their personality after giving birth is plain stupid. No one is good at parenting from the get go. Some people learn fast how to do it and some don't. DEAL WITH IT. It doesn't make them a bad parent.
4. If you don't like the main character of a Webtoon or manga from the start, just stop reading it instead of making a fuss in the comment section. No one is forcing you to read and no one cares if you read it or not.
you did not just call the mc ugly! why the fuck are you reading if hes so damn ugly then! how are you going to come into the comment section and insult the mc, why did you even read up till now then? and no one is crying about it they just pointed out how dumb and stupid you and your comment are (╬ ̄皿 ̄)凸
The mom is jealous of the child... when I tell yall hes the worst omega mom, my god
