mark Lee is my boyfriend, it's been 5 years since you we're in relationship. We sharing a flat together as we both study in SM University but different major. Mark lee takes psychology and I takes law major. in last year, our relationship becomes a bit toxic. You saw him having fun with other girl once, but everytime I brought this up and ask mark about it, he always denying. Mark lee is a popular guy, it's natural if he attracted other girls, but I can't also deny the feeling of doubt and insecure I have everytime I heard mark lee talk to other girls. Sometime we becomes so intens. If he's in good mood, he likes to wrapped his arms around my waist, kiss me slowly and start touching my body gently. Otherwise, if he's in bad mood, his so careless with my presentage, even i do nothings wrong. I'm just so confused by his behaviors, but i still trying to understand him. His not a bad guy, he used to be gentle, kind, lovely, sweet, patient, and kinda jealousy and possessive. But tha past year, he becomes more jealousy and possessive.
