Everyone loves Abby, but doesn't know how to make it work.
When Jinu tells Abby that he loves him, Abby immediately starts stripping because he thinks his physical attraction is all he worths. Jinu doesn't complain and sleeps with him. Abby believes that Jinu is just like others, he only likes him for his body. Abby becomes sad but keeps offering his body everyday. Jinu has no idea what is wrong with their relationship, confused by Abby looking more and more miserable.
Romance, on the other hand, wants to take it slow. He kisses Abby, praises him, and smiles at him, but never dares to touch him intimately. Abby starts to worry because he knows he has a good physique, and Romance doesn't seem to want any of it. "Do you really love me?" Abby starts to ask nervously, to which Romance always answers with, "of course, dear." But Abby isn't really convinced.
Baby also has a hard time making Abby believe that he loves him. He gets impatient and spits out, "fine," and stops paying attention to Abby. He no longer climbs onto Abby's back, pokes him when he is asleep or lets him lean on his shoulder. Abby panics and pleads him to act like he used to, but Baby is stubborn and tells him, "you are the one who doesn't want me to love you anymore." Abby secretly cries every night.
Mystery never confesses his feeling to Abby because he doesn't know what to do with it himself. Abby notices that Mystery might be in love with him, but he can't ask him directly because he may be wrong. He can only wait for Mystery to make some kind of move. But he never does. Eventually, Abby gives up and starts to believe that they are just good friends, nothing more.
Everyone loves Abby, but none of them dares to act on it because they know what happens when they do.
