The one i'm looking for is the loan shark one where this dude is a very kind person who fell in love with the loan shark. On his very last payment, he refuses to make payment and lies that he didn't have the cash envelope. The loan shark warns him but he still persisted because he wanted to keep meeting the loan shark. Hence the loan shark decided to carry out punishments and made the guy give him a bj. Afterwards, the guy finds out the loan shark helped him to pay and went to their HQ and confessed. Then they went back to the apartment, sex-ed and the end
