I feel like slapping hyun, like wdym "I've decided not to be stuck between the two of you anymore" his basically the one going to them. I can't wait to see the look on his face when he will get rejected twice.
The boy is a pushover he is shy and he can't stand up for him self, because of how he is treated in his household, if the mom never compared him to the brother and just accepted the boy for who he really is, I don't think his personality would be like this.
