Mark got you pregnant after one night stand. But, you didn't tell him about it because you want to surprise him on his birthday.

His birthday came 2 months later. You're ready to surprise him about you being pregnant. As you're about to open the door, you see him kissing a woman. Mark immediately noticed your presence and stopped kissing that woman.

"B-baby... It's not what it looks like...." He says as he approaches you with frown on his face.
