To be completely fair.
The girl in that one is 1000 times worse.
Cause at least this one has feelings for MC, and doesn't try to cuck him.
Sure she's a spastic and has zero social awareness and doesn't realise she's abusing him.
Meanwhile the chick in the one you posted, knows exactly what she's doing.
p.s. not saying the chick in this new story isn't responsible for her actions, she most definitely is, but they are more redeemable, since the backstory is, she's a massive idiot that has no idea how abusive she is actually being, and is just a coward afraid to lose him... which is ironic cause she's the one that drove him away.
i.e. an ignorant idiot. So they have hope of redemption... if the grandpa stops being a moron and pushing her to act that way as if it's acceptable.
I wounder if there will be an arc where she realizes all her friends are fakes.
