"I, I have always liked Oniichan ......"

I think it was natural that ”Tsukimino Fujiya“ came to like ”Ichika"-chan of childhood friend.

She seemed to have the same feelings, and my sister who knew it pushed me back.
I was trying my best to hold hands, but I was happy.

But one day, my sister suddenly became a recluse.
she became an idol, and her passion with the actor was reported――

i believe in ichika.But.......

When I woke up in a sense of incongruity that I was asleep before I knew it, my sister's “wormwood” was there, as if straddling me.

"So I decided.Oniichan will make me happy."

「私、ずっとお兄ちゃんが好きだった……」

俺――“月御之藤弥”が幼馴染の“一華”ちゃんを好きになったのは当然のことだったと思う。

気持ちは彼女も同じだったようで、それを知る妹が俺の背中を押してくれた。
手を繋ぐので精一杯だったけど、幸せだった。

だけどある日、妹は突然引きこもりに。
アイドルとなった彼女は俳優との熱愛が報じられ――

一華ちゃんの事は信じている。だけど……。

いつの間にか眠っていた俺が違和感で目を覚ますと、俺に跨るようにして、妹の“よもぎ”がそこにいた。

「だから決めたの。お兄ちゃんは私が幸せにするって」
