The semes are twins and they look practically the same, one's more laid back and seductive (jaewoo) and the other one is shy and timid (saewoo), the shy one really loves the uke but is too timid to approach him so he begs his brother to do it for him instead and pretend to be him. But that backfires since jaewoo (seductive guy) starts to like the uke then uke finds out abr everything then yatatata he picks the timid guy.
Honestly when i first found out abt who he picked I was a lil dissapointed (i mean i still am since i wanted poly so bad) BUTTT... saewoo (timid guy) is actually such a sweetheart and he truly loves the uke and me personally i think jaewoo, the other twin, only liked the uke since in ther childhood all the attention was on saewoo so finally when the attention wasn't on him and he had something from saewoo i think that's how he started liking uke.
