I think so too when read the raws. The uke love the big brother but he's a womanizer so they broke up. The little bro thought he was a replacement when they're together and try to be different from his big bro and slowly take the uke's heart. Ultimately the uke love the poor little brother :/ if it's like that i hate the story :/ i love the replacement twist better :/
But it's boring (to me :'( ) I feel sorry for the little bro, he knows he's replacement but still try to make the uke love him : ( and the uke's love for him a little bit reluctant, like I will love someone who be good to me and quickly forget the fact that he's my ex's brother, it sounds real but it's too old : ( i dont hate the characters but the plot made me disappointed :(
Not gonna lie, wish they weren't brothers. Until it's translated I'm gonna pretend the uke isn't using either of them as a replacement and is just having trouble moving on from a 2 year relationship that ends in a pretty crappy way, so him getting into relationship with lil bro is just too soon for him... I wish the plot was more interesting too...

Found link in an earlier post (●'◡'●)ノ , it's to download the vol not read it online.
Looking at the raws seems like the uke actually does like big bro, maybe? Big bro's pretty much scum so not like it matters lol.
