she abandoned hyesung while he was a child, knowing fully her husband is piece of shit. and then she never went looking for him at all. she then meet him again after she knows hyesung married to a famous artist. and when she had the chance to meet hyesung. there's no apology, she gaslights him instead. she's just terrible mother
waking up to many people under my comment omg hello yall haha but also aaa thank you for the refresher on the lore! now I really hope they don't patch shit up with the gaslighting abandoner idc about blood, she's just straight up awful, idc if her guilt is now eating her up now that she getting older (am I just being biased and projecting as someone with mom issues? maybe)

I legit can't recall much about what the grandma did and I really don't wanna reread the main story
