Before my reincarnation, I was a former delinquent and a top-class brawler who was once called the Crimson Rose or the Crimson Demon, who had gathered the interest of other delinquents. Its easier to talk with fist than to talk about love, so naturally my romancing skill is zero.

In order to protect my life while cooperating with the investigation of the incident, I will try my best to fall in love, but... The person herself hasnt realized it. Serina, the daughter of an Earl and a former delinquent, is cherished and loved by her surrounding. This is the story of her journey to obtain happiness.
