(I never made a mother's day thing... I guess I have to now, huh... I may not actually cause I'm growing irritated by writing these...)

You walked into the living room and noticed that it was quiet but the atmosphere felt slightly tense. You peeked in and were surprised to find Raijin and Ace sitting on the couch in silence.

Ace: "..."

Raijin: "Do you... request something of me, Ace?"

Ace: "No.. Just... Happy Father's Day.. father..". He muttered causing Raijin to look at him, his eyebrows arched in surprise.  " T-There.. I'll be going now-"

Raijin: "Hold on."  Ace was about to get up but paused and looked at him. He watched as his father took his son's mechanical right hand before tapping it. You watched as the metal arm began to grumble and fall apart, only for something to take it's place.. Flesh and blood. An organ arm had grew back.

Ace: "W-What the...!?"

Raijin: "Consider it... A thank you... And an apology.."

You watched the entire scene, surprised at what Raijin had done for his son. It showed that after all this time, he still cared for Ace in one way or another.
