he is not taking her side. he knew that he was and always be love by his mom thats why he regret wht he said! he is young we all make mistakes
?? "Did you ever hear her side of the story?!" Lol unless I read that wrong and I'm illiterate doesn't that imply that he's siding with her? Although you're right abt him regretting what he said, but that still doesn't excuse the fact that he still took her side for a while.
Imagine taking the side of some random old lady you barely even know over your own mom that raised you and always treated you good..Yes, they both abandoned their child, but Hyesung came back and made up for his mistake and showered Byul with all the love Hyesung could give that his mom never did.
