Taka ga Fukuen

Synopsis

1-3: The reunion of two people who were sex friends in high school, 20 years later, when one of them is a lonely soul fast passing marriageable age but still dreaming of his first love; the other, a cold, business-oriented man who wants nothing more than to forget their past together. 4-5: A rape victim hides information from the police, thinking his attacker loves him. A certain police officer is determined to shatter this misconception and nab the rapist, but his methods end up being a bit... unorthodox. (Source: MangaDex)
