I just completed the novel and wtf the ending was literally as if yuseong and dojin was getting married.
(╥﹏╥)/ . Yuseong wore a white suit and dojin wore a black tuxedo. They literally walked down the isle, all the friends and family to witness their oath as they confessed to eachother. I guess everyone regarded them as a couple anyway. All that lacked was just a kiss. Puff.
