– There’s only one reason: Yomo hates them.
– Uta, however, being the drama queen that he is, probably responded to Yomo’s discomfort with his tattoo by luring his boyfriend in with a promise to remove them.
– “Okay…” Yomo says, slowly, waiting for the punchline.
– The punchline is Uta probably then chopped off his own arms and let them grow back as “removal.”
– Yomo is horrified and says it doesn’t matter that much.
– Uta: “I know. I just want to force you to take care of me.”
– Yomo turns to stomp away, but then Uta calls out and asks if he’s really going to leave him to Itori’s caretaking.
– And that’s how Yomo spent a week nursing Uta in bed.
