What is going on woth the uncle rabbit? I thought he was dating the tiger?

Spoiler I guess?





He almost got assaulted at a bar and Mr. White Bear saved him, but because uncle rabbit didn't answer tiger's messaged he got mad, then because he saw him with Mr. White Bear he got jealous and tried to attack him and that's when Mr. White Bear stopped him
The blue ox? Cow? Bull? Is kinda just there to be the 2/3rd male lead I guess
