Tamaki was always a good boyfriend, but he was very shy and insecure, but he wasn't very jealous either. Recently, you were going to a restaurant, when you met someone who was very important to you in the past, your ex-boyfriend. Your ex was very friendly with both of you, of course he sometimes teased you and that, even though Tamaki wasn't jealous, made him jealous, especially when your ex-boyfriend mentioned the nights you had with him or the moments of you.
