I love seeing more realistic types of couples!
Many fujioshi will discriminate against "bara" type ukes because of the traditional way of seeing bigger body types in a more masculine way. Feminine/small semes are seen as awkward and weird.
However, the plot for this story mainly works because of their body types. Haewoon was scared because he was smaller than Taesik, and Taesik seemed unapproachable due to his big build and disinterested face. When they were together anonymously, body type no longer mattered. They fell in love because they were compatible with each other, not because they were compatible aesthetically. It's a light-hearted story with a message to "follow your heart because that is most important". It is also realistic on portraying the modern gay couple.
Daniel has changed so much as a character, and although I am happy he got back his other body, I am much more excited about his character development and newfound confidence!! He's no longer the weak pushover that we started off with and I'm so proud.
