You Think You Can Escape by Transmigrating, Brother?

Pure forced love, but the male protagonist has stomach problems and his stomach churns when he sees the female protagonist

The author is a bit like a female channel. This is one of them. There are still many shortcomings, but the part about tormenting bt masters is pretty good [face covering] Author, please don't do it. You suddenly made me lose my mind. It feels so good, ahhhhhhhhhhh, ahhhhhhh, ahhhhhhhhh? !

I guess the prototype is that comic, it's pretty good.

I have a memory of reading a Japanese novel a few years ago.

The titles are all about the older brother. Those who didn't know better thought they were written from the younger sister's perspective. If you are not the author, when did you change your worldview?

The protagonist must defeat his sister [laughing evilly][laughing evilly][laughing evilly]

Although I admit that this is very similar to a Japanese comic, the development and the specific situation of the characters are far different.

Every title has the word "brother" in it [Thinking]

The author is great. In the end, was it HE or BE?

Single heroine? Is the heroine a younger sister? I'm very curious about how to write a story about how the male protagonist can fall in love with his sister if the heroine is her sister.
