Story is somewhat slow and it rushes at the end.
The romance here I felt it a little forced at the beginning but ended in a good way.
Yes, this is a typical girl dressed as a boy drama, and the reasons of the change even though they are interesting and more realistic (that other dramas with that play with the female as a male), were executed poorly on some points.

The chemistry between not only the two main characters, but the four main as friends were the best of this drama, each one of them portrayed their character in a really nice way.
