Y'all shouldn't get pressed at Hyesung and understand him a bit will ya? Other than Math, Hyesung lacks in a lot of things. He's just worried that Byul might end up like him, he obviously doesn't want his child to experience his trauma. This is a big pressure to someone who was neglected in his whole childhood, and a young parent at the most.
To cut it short, y'all don't have Asian parents and it shows :)
Let me add: Hyesung's a great parent(mother?). He chose to go home and take care of Byul (as he should) instead of going for his college party life which he never had before.
