Luo Yiyang unilaterally decides that Zhou Lindu is his rival in love.
After countless secret competitions, he realizes
that Zhou Lindu seems like a pretty decent guy.
So he happily becomes sworn brothers with him.
Then
when Zhou Lindu earnestly and gently asks, "Could you consider me?"
Luo Yiyang, of course,
of course turns him down! Hey! I thought you were my brother, but you think of me as your wife?!
"N-no, that's not happening," the pure-hearted male high schooler declares righteously.
"It won't happen...?" Zhou Lindu lowers his head.
"It's happening whether you like it or not."
