I'm sorry, but the issue is not with him for how much contact he has with the new girl, someone who he is related to and who he considers a sister, it's with you and attempting to imply that there's some sort of pedophilic intent involved.
Those were some amazingly silly faces. Thank you so much for the double chapter.
Besides that, loli doesn't have many options here... other than just stripping in front of him and jumping on his dick. She's sister-zoned so hard. As a guy he could probably still fk her if he tried but it'd be like a pity fk, which are terrible.
@yuu-oniichan she has the option to say that she loves him romantically and then compete normally without relying on his brotherly affection. However, if they're high schoolers the age gap is too big. She'd have to hope he's still single when he's in his twenties or something.
@firosahoge yeaaaaa you think those two three thirsty girls are going to give him 5+ years of respite so another (known) opponent can sneak in and steal their thunder? Especially not with that maid around, lol.
Hmm? Actually, it might be a good idea for the loli to get him arrested or defame him enough that the other two girls give up on him. Or, go full yandere. Yummy. Or maybe an eromanga-sensei route might work, and go full neet?
