Lin Xi, who has an innocent and lovely sister, suddenly regains the memory of his previous life when he wakes up.
She was originally a social animal who died suddenly while working overtime, and her lovely sister Lin Anan was the heroine in the Otome game "Love Message".
Lin Xi is a vicious villain who bullies his sister and is jealous of her being surrounded by handsome men.
These were not enough to shock Lin Xi. The most terrifying thing was that the targets of his sister's attack were all dangerous people with twisted personalities.
The childhood sweetheart next door is a highly intelligent anti-social personality. The classmate in elementary school was a well-behaved young lady at first but later turned into a delinquent. The classmate in junior high school is a sinister person who appears to be a prince. The senior in high school is sunny and cheerful, but is actually the reincarnation of a jealous man.
To protect my sister's chastity! Lin Xi embarked on the road of beating mandarin ducks to correct the distortion!
Go away! You bugs, don't pollute my lovely sister!
As she continued to fight, Lin Xi discovered that things didn't seem to be what she imagined. The "quasi-brothers-in-law" were becoming more and more strange. Could it be...?
