Are they or aren't they? Yes or No?

The poster really says it all.

In Yes or No (Yes or No อยากรัก ก็รักเลย, Yes or No, Yak Rak Kor Rak Loei) a college girl named Pie (Sucharat Manaying) has a tomboy named Kim (Supanat Jittaleela) as a roommate

They have their differences at first. The girl thinks the tomboy with the Korean pop-star hair is a guy. They divide their room in half with a line that shall not be crossed.

But they eventually become friends.

And perhaps it will be more than friendship?

There's a trailer and you can watch it here.
