Once you touch me no one can touch me [Kim Namjoon]

As soon as Y/n comes inside the house, Namjoon throws her jacket to the other side, he goes to Y/n and kisses her, both take off each other's clothes,
Namjoon picks up Y/n and takes her to her bedroom, both passionately kissing each other.
Neither of them knew that it was their first time
both love each other,
After a long hot session, Namjoon and Y/n were sitting near the big glass window, both naked, Y/n wrapped in a sheet, she puts her hand on the glass
Y/n: What a beautiful view isn't it?
Namjoon was staring at Y/n
Namjoon: Yes,
Namjoon's gaze goes to Y/n's hand where there is a ring on her ring finger.
Namjoon: Are you married?
Y/n: No, I am engaged
Namjoon's face turns sad
Namjoon: Oh, so you cheated on your fiancé.
Y/n: what difference does it make
