He's Lee Heeseung. He's calm, quite and grumpy. but he's a gentleman. you're Ari. his best friend. you both are very very rich.you tow made a rule for your friendship. it was 'never fall in love with each other'. it was made by you and he kept it perfectly but you....you yourself failed. you fell for him. but he started dating another girl named Zara. so....you decided to move on though it was almost impossible. remember, almost impossible but not impossible. bcz you didn't want to ruin a healthy relationship. but Zara is not a good person. he was loyal to her but she? she's been cheating on him from the beginning. you saw it and said it to Heeseung but she calimed that you're jealous. that you're trying to break them up by lying bcz you love him too. but it's not true. you just wanted him to be happy. but Heeseung believed her and blamed you instead. and this made you actually moved on from him. you don't know why but you started feeling no interest in him. but you still didn't leave him. You respected your friendship so much. but you knew how Zara is using Heeseung. so you even requested Zara not to do this. but she said 'he's nothing but entertainment to me' . you felt so bad for Heeseung and said him the truth again but Zara again blamed you. and Heeseung believed her lies. though Zara knew that you don't love him anymore, you moved on; she kept using your earlier feelings as weapon. and Heeseung? he actually insulted you again. but this time, you were ACTUALLY done. and decided to leave him. but Zara said and he thought you'll crawl back to him. you're being dramatic and trying to get his attention. and he won't give you the satisfaction. but you actually left. and you decided to never look back.
