Considering how early he became a mom, he hadn't finished growing up (￣∇￣") I'm glad he's happy and the alpha brings out that side of him. He's even growing in other areas like he's shown showing interest in his studies again. I get what you're saying but I have a different perspective
I even feel like him being spoiled wasn't enough compared to all the misery he'd gone through ╥﹏╥
he was a kid who was forced to mature early, he being childish now is a win. shows that he's comfortable with his alpha to be like that, I this it's very cute.
Bro I’m sorry but the omega was so mature and now it’s like he’s a kid himself, I don’t really like it
