Honestly...

Yup my parents also have favoritism it's not that deep though cause i talk about it openly with my family and sometimes i bully my family making them guilty towards me lol it's fun anyways yeah quite sad but I'm sure once the ice boy develop some feelings toward our female mc (not in a romantic way pls stop) he's gonna be alright

Exactly it was HIS birthday but the father came carrying MC, and gets ANGRY when the poor soul tries to impress him. After all this that pos has the AUDACITY to give the BIRTHDAY boy a DISAPPOINTED look..
