the arc where the MC has to make the 6 princes fall in love with him. HAHA the struggles of the MC not to be found out that he was cheating the princes was priceless
the MC and ML had a long dream of what might happen if they met in the real world.
Especially when the ML cheated on him, he wasn't swayed with whatever bullsh*t explanation the ML did, and prepared to leave him even though as far as I can tell, the ML was the only light in his life.
The MC's personality is pure but he has a poisonous tongue which often led to a lot of misunderstanding about him which made me laugh ^_^.
It took 101 chapters until they become a couple. I was seriously worried you know.
