It definitely will since it's an adaptation of the novel, and it's followed it so far
What happened? Please spoil mee I can't suffer any longer huhu
After enduring the abuse from those 3 Haewon tries to commit suicide but instead he survives with injury and suffering amnesia (memory loss), the 3 guys suffer guilt and realize the consequences of their actions, haeyoung experiences massive regret and treats haewon kindly once again and doesn't tell him about anything that happened before hand, long story short haewon and haeyoung end up together
I hope it doesnt follow the novel.....
