@I wanna fu** nanami so bad sorry to say hun but it's all in the psychology. ofc it is bad and unforgivable for him to do that to suyeong but it is clearly not an excuse, it's a trauma response. It is when all you have been taught were "this and that", which is why when you are being subjected to new things or feelings that were never introduced to you before, you ofc tend to approach it in a way that is familiar to you. Whether it is a good or bad approach. Him treating suyeong like that is HIS CHOICE. However, it is crucial to understand how his unconscious motivations made him act the way he did. (not downplaying his wrongdoings, just explaining it more psychologically)
can't stand ignorant bit**** who thinks they know better lol
