Summary

“I heard you’re really good at sex.” Jinyoung, known among his friends as “Sex Professor,” is actually inexperienced and as single as could be. However, when he’s questioned by his 20-year-old sister, Bom, Jinyoung pretends to be experienced and lies. After that day… Every night, my sister now comes to my room without our parents knowing. This is a problem.
