I think you have a problem. You told me that you had been, "working" on trying to get me to like you and you are disappointed that I am with someone else. You do realize that you are in a relationship with someone? Even before I met my Jagiya, you were in a relationship with someone. The fact that you were trying to get me to like you while you were in a relationship and admitted that to me completely floors me. I never had a connection to you in that way and I won't apologize because even if I ever did this shows me that you aren't the kind of person I would want to be with anyways.
I am happy with Soohyun and even though we share a face, we are completely different people. We look the same and are similar, but we are also different and compliment each other. I've been nice, so now that I have spoken my mind don't come back to me upset or angry or anything. If you decide to attack me or him for us being together then we don't have to be friends either. It is really up to you. I love him and so if you do anything to him you will bring my wrath unto yourself.
Also, you should appreciate your partner more. If I were you I would man up and let them know what you had been doing; I am a gentleman so I'm not going to be an ass and tell them for you. If I see or hear about you doing that sort of thing again though I have no qualms with telling them. You shouldn't be in a relationship if you are more worried about "bagging" other people.
