Kaito and Gakupo were hanging out at Kaito's place, they were having fun watching movies, doing Gakupo's hair, and stuff

They wanted to paint their nails, purple for Gakupo and blue for Kaito, so the colours matched them

Gakupo had Kaito in his lap, he had finished painting his nails, though Kaito wasn't done yet, he was slow

He took Kaito's hand and started to paint his nails purple, like his own
