The Sun and the Rain (muitan)

Kanano cheated on Tanjiro with Zenitsu. Poor Tanjiro was heartbroken and devastated at that time, but he couldn't change her mind. A broken heart needs mending and over time it'll heal and get over the thing or someone that is causing it so much pain. A hashira becomes aware of this, one with cyanish tips and mint eyes. He looks at clouds and didn't pay attention when he first arrived at the demon slayer corps, or did he?
