can anyone spoil me on how bad the 'manipulation' was? and why is everyone saying that the...

Eh compared to other red flags it's like a 5 out of 10

Have you read ‘Will the roasted beans sprout’? If you did, then you know how far manipulation can go. The good news is that in this story; jigeon manipulation is not as bad. The little bro Jiseok just seemed more happy go lucky and easier to be with in my opinion.

He's more like calculating

Honestly, neither brother should be with him. The lil bro KNEW MC was in love with him and ignored it for years until MC's affection towards him was going to taken away. So no, lil bro is not a good choice. Honestly, I feel like he only fell for the lil bro cause he reminded him of the older bro who was his soulmate at first. I mean, a good thing that older bro left and didn't jump him early. I only like older bro more because he jumped on his chance to be with MC. He also thought he had no shot before because MC was in love with his little brother. I also do not like how manipulative the ML is. He is always scheming trying to get MC to look at him for who he is and not his brother.

It's crazy that you'd want him to be with someone who took his feelings for granted just because he doesn't have the ability to out scheme someone. Little bro was ready to do anything as well to get those feelings back to him, so he could enjoy them again. MC tried to move on and he couldn't stand that.

Ok that’s fine ╮(￣▽￣)╭ I don’t mind being called crazy. They're both fine guys and it’s fictional. I just noted and answering OP what are the possible positive things other readers pointed out about the younger bro. They asked ‘why do people say mc should’ve been with the little bro’?

Gosh…It doesn’t have to come down to a ‘no you’re wrong. He took him for granted. Your opinion is crazy’ #－.－)

The little brother is far more of a red flag than the ML. ML was manipulative, but only to get MC to notice him since MC was busy being trash around by the little brother. All ML’s action was to get MC’s attention. Little brother only tried to win back MC when he found out that ML is making a move and he didn’t want to lose out on having someone always being there for him 24/7 like a slave. Side story sex wasn’t the best compared to others.
