Tim had been dating Rudolph for a year and a half before he found out that Rudolph was a werewolf. It started when Rudolph accidentally got drunk and insisted that Tim touch his tail.
Tim: Sure, sure, I'll touch your tail. (Indifferently)
Rudolph: You promised! My tail feels really nice~ (Offers his tail)
Tim: Mm-hmm, sure, it's nice... Wait, what??
The next day, a sober Rudolph looked at Tim, who was staring at him with a smile, then at the tail Tim was stroking.
Rudolph: Goodbye, friends. I'm going on a long journey.
