To be fair his bestie (Im assuming you mean the girl) wasn't in the hospital because of Tae...it was because of her boyfriend which is a whole separate matter. And then the guy who took his life had little to do with either of them. We were given the context that Tae made it clear on his boundaries in that relationship and it was the guy guide who took it too far. Tae never outwardly harmed him, he just canceled the contract; which if the guide stuck to the boundaries, wouldn't have caused any harm. You cant blame someone for someone else's incorrect actions just because that persons actions led up to suicide????
Tae was clear, he was just a guide to him. And the guide fell into love and despair on his own.
Why blame Tae when he never led him on?
People get obsessive about others and either stalk, harass, or hurt the object of ththeir obsession while others...take it out on themselves.
So Lee yeoni saw his best friend in hospital cuz of Tae and also saw a guy taking out his own life bcoz of Tae and still lovey-dovey with that mf Tae?!
