Well ig the author left it for us to decide wiether they end up together or not .... Whatever  we wanna think of. I personaly will belive that The red hair took his sh** together , did a pretty decent job at overseas . Learned to behave for siwon sakes and came back years later to express his love  This time he didnt blackmailed the top rather kept expressing his love in a healthy way . And after a long hard time the top finnaly accepted his love and they started dating each other .  Later the top moved his bar to overseas with the red hair . And even tho they had complicasis every once in a while they remained happy  Thats just me beliving . Oh and btw someone said that the main couple broke up in the side stories . Id personaly like to slap u on the face fo this false information . That made me loose my shitt fr
