The hyesung and his mother's situation is not comparable. Byul was an unwanted accidental pregnancy, but what hyesung's mother did was worse.
She left her child behind to be alone with his abusive father - knowing full well he would do to him what happened to her (pimped to alphas) if he manifested as omega -
all so she could be with another alpha. And she didnt want her lover to know she had a child. She only showed interest in being part of hyesung's life when he got revealed as being the partner of a wealthy celebrity and married into a rich family.
Shes scum and filth. And shame on byul and dojin for dismissing hyesungs trauma and feelings by gaslighting him.
Why did byul feel need to meet that woman? When he already basked in affection by his father's family and parents. Spoiled brat.
The fact the grandma met with byul behind her son's back shows shes a nasty schemer. That doesnt respect her son.
