It's hard to travel through time, and it's even harder to travel back to the person you were two years ago in a parallel space.
Kiritani Suguha raised his middle finger to the sky expressionlessly, shouting in his heart: Fake, obviously the two worlds are almost exactly the same, but why did those idiots in Takamagahara turn my general offensive cousin into this cute otaku? This is unscientific! ! In this world, it's okay if the brother becomes a little bit smaller, but brother, you actually got picked up by Mary Sue. This is so cruel, give it back to my BOSS sister-in-law! (You know what Takamagahara is, the place where eight million gods live in Japan, the heaven of Shintoism.)
This is a story about a fujoshi cousin from a parallel space who worked hard to win over her cousin, punch Sister Su, kick her lover sister, protect her brother's chastity, and help him pursue his "sister-in-law", but was ravaged by the "sister-in-law" as a little fruit with potential for growth.
Brother Shou: Sister Su is so scary! (>_
