I don't know which season and episode it is.

The first hit, hope to adopt.

The abbreviation of OAC(Christian and Oliver) is a branch of the German longevity TV series Verbotene Liebe. The play mainly tells the love story of Oliver (played by Joe Weil) who returned from a sailor's life and Christian (played by Torre Schloemann), a staff member of Unlimited Bar, who fell in love because they shared a room.
