I agree the YTC MC was insufferable. Whiny while not setting his boundaries properly. But Siu is really similar. He doesn't draw a line with either of them. Just being willfully ignorant. Like, don't make out with the dark haired one if you know you'll hurt the other one and then lie to him that nothing happened. He doesn't blame them for his shortcomings, but it's still a bit shitty...
This reminds me of yours to claim...I hate love triangles like this
