Mr. Seo was the head of the first entertainment company that Shiwoo was a part of. Because Shiwoo looked up to him as a father figure, Mr. Seo took advantage of his nativity and raped him. Mr. Seo thought he was already sleeping around but when he figured out that he was a virgin it made him want to sleep with Shiwoo even more. Due to this, Shiwoo became promiscuous because it was the only thing to get his mind off of things, it made him feel valued, even if he regretted it afterwards.
So you could say the beginning of everything going downhill is Mr. Seo’s fault.
Thank you for the clarity.
What happened with Mr. Seo? What did he do to the uke?
