That is Geonwoo in the above image. It is a portion of a larger image that includes both of the guys. Do a search for 내가 원하는 건 and you can see other images. It's unfortunate the the author decided to make them look like twins except for their hair. Geonwoo's hair has a part in the front so it almost always easy to tell it's him.
Its a hard pick. And it kills me I can't really tell who is in the cover photo lol. I think Haewon. Geonwoo is a great guy but I think he could rebound quickly and has a lot of options. Haewon has secretly been into fl for years and lacks confidence. I'm hoping he gets the confidence or fear of her getting with Geonwoo as the motivation to let his intentions known.
