I think that Nanjo couldn’t say no to Sunhwa, since he’s soft hearted towards Sunhwa. And basically Nanjo expected Mokyeon to reject the 3some, since they have a contract. But then Mokyeon got big mad, knowing that if he doesn’t join the 3some, Nanjo and Sunhwa would just have sex on their own. So he joined to interrupt them - which he sort of did, since he lowkey tried to kill Sunhwa for wanting to hold Nanjo’s hand lol
But what is the point of this 3some? What does sunhwa even wants ? He's continuously having 3some with his fuck buddies how does this make him an innocent person? If he's okay with 3some then what's the point of the contract then? It doesn't make any sense tbh.. i don't get some of the things they are doing and its not even clear
I still don't understand whats the point of 3 some in the story.. isn't this 3 some breaking the contract nanjo and mokyeon did? Nanjo's initial plan was to stop mokyeon from having sex with that bottom red head right? Then they went on to have 3 some so what's the point here?? The story doesn't make any sense... And if the red head bottom was so innocent as per nanjo then why is he having 3some ? What kinda innocent person has 3 some with his so called fuck buddies.. there's a huge plot hole here that doesn't make any sense...
