My Cosplay crush is actually a Guy?!

Han Seong-hee has loved cosplay ever since he was little. Because of his naturally pretty appearance, people often mistake him for a girl and some even bully him because of it. But when he puts on a wig, makeup, and costume, Seong-hee becomes "Sae-hee," a beautiful and popular cosplayer adored by countless fans.
At college, however, Seong-hee keeps his cosplay life completely separate from his everyday identity.
Then one day, his classmate Oh Hyeon-chan comes to a cosplay event to support his friends. Hyeon-chan has never been interested in cosplay before, but everything changes when he sees Sae-hee.He falls for the beautiful cosplayer at first sight.
There's just one problem: Sae-hee is actually Han Seong-hee, his own classmate. Seong-hee recognizes Hyeon-chan immediately and desperately tries to avoid being discovered. To his surprise, Hyeon-chan doesn't recognize him at all. Instead, Hyeon-chan becomes determined to see Sae-hee again. As Hyeon-chan grows closer to both Sae-hee and Seong-hee, he begins noticing strange similarities between them. Meanwhile, Seong-hee finds himself developing feelings for the very classmate who unknowingly fell for his cosplay persona. But when the truth finally comes out, Hyeon-chan must confront a question he never expected to ask:
Did he fall for Sae-hee because of the cosplay or did he fall for Seong-hee all along? A story about cosplay, friendship, self-acceptance, unexpected love, and discovering that the person behind the costume can be the one you've been looking for all along.
