Caster feels bad.  He hadn't meant to cause Yong any harm when he made him that cat cupcake. Quite the opposite, in fact. And he didn't even know how it managed to come alive without him noticing, though he supposed it was because he hadn't even known he could do that at the time. But the point was that he messed up. And he had to apologise.

Caster approaches Yong and grabs him by the arm in case he runs off.

"I know I messed up, and I'm sorry. I didn't know that making a cat cupcake would have anything to do with your past."

Caster pauses, and takes a deep breath.

"You had right to be mad at me, but you shouldn't have brought Lavvie into this."

Caster lets go of Yong, unconsciously fiddling with his gloves.

"It's just... seeing Lavvie covered in red... brought back a few... unhappy memories..."

Caster goes quiet. Remembering how he had failed to protect his sister.

Yong looks at Caster and blinks, his expression turning from annoyance to sympathy. He understood people with traumatic experiences, since he also has a case of trauma himself. He then gently grabs Caster by the arm and faced him. "I accept your apology," he started, looking down at the ground. "I.. I guess that I also have to apologise. I never knew that having red paint on Lav would bring back trauma, but I swear it wasn't on purpose."

Caster gives an empty laugh, before snapping out of it, "I know, it's not your fault, you couldn't have known, and it was an accident. I... really should have put more thought into it before declaring a war..."

Silence took its place in the atmosphere. Yong sighed, and put his hand on Caster's shoulder. "Mate, i-it's fine. I understand how you would've felt doing so." He raised his hand and shaped it like a fist.

"We cool?" he asked.

Caster chuckles and smiles, "We cool." he says and gives Yong a fistbump.
