Bahahaha idk even know how I seen it! Maybe it's just one of those things because he's a high class looking guy, I'm thinking hmm I wonder if he hides his hickies (≧∀≦)
Yes! I think it could be, I hope we do get a few chapters at the end with them since we're getting doyuns brother and his doctors during the series ヾ(❀╹◡╹)ノ~ or the friend talking about his love life with doyun to help him, not sure but hope we get something (≧∀≦)
Guuuys look at the friends hubby's neck, not sure if it'll work but the part where he greets doyun to jump in the car
