Mark's POV:
Tom: Where is Alex, Mona?
Mona: He is sleeping beside Anna...
Tom: Wow that's really great, so finally I got time to spend with you.
Mona: Tomm..!
(Mona's face turns to blush and at the same time she is trying to give warning to Tom and I understand Tom is eagerly waiting to sleep with Mona alone but Alex is killing their private time. Actually, Mona is giving priority to Alex over Tom, so I guess Tom is exhausted with it, but no, so far I know Tom like kids and he also likes to tease Mona maybe thats the reason he is teasing Alex to taunt Mona.)
Tom: What?
Mona: How shameless you are...
(Mona said with her pout face.)
Tom: I will be more shameless the moment you entered my room, Mona, come fast...
(By finishing his words he hold Mona's wrist and Mona immediately screamed at him.)
Mona: No need, and for your kind information Mark is sleeping with you, Anna Alex and I are sleeping in my room...
