[Well, that's a surprise. Hijikata had no idea that Gokudera and Zuko were together on another world before Avalon! He simply assumed that Zuko's friends were worried because he'd been hurt by some other partner before.]

So the two of you go way back to multiple worlds ago? And all his friends were on that world with you too? Regardless, going from "I tried to kill him" to "He's my boyfriend now" is one hell of a development. 'Enemies to Lovers' rarely ever happens in real life!

[What is he calling "real life"...]

Whom else did he leave behind here, another boyfriend or girlfriend?

[He thought it was just a tricycle! Are there side branches?]
