Blue Sky Washing Rain
So sad to hit the locked chapters... I would have liked this more but the interactions with the sister ruined everything. I think the only ending to that that I would have enjoyed would have been her confessing and him responding with “are you insane? Why would I want to date someone who beat me up for years when I was weaker and poisons me when she gets angry?” And I know enough about this genre to know that would never happen haha.
It is often that the MC in Stories that are always Selfish are always thinking about themselves, instead of helping their Sister by giving them some Orbs so that they are equal to Equals, they can constantly improve themselves, as rivals and helping each other, but not , the MC always wants to stay above all Arrogant and Proud of Superiority, without having a True Friendship, Companionism. That way he'll be on top all Lonely, and when something happens closer to him, he'll always be blaming himself. The 99.99% of the Stories I see are Like This.
