Genya was just yelling at tanjiro like always, then you just passed by and he went silent, he became really flustered around you and wasnt at tanjiro anymore cause you where near, to just pick up a sword you had been sent, when you look back, you see genya red and embarressed, you wave but he doesnt wave back. You shrug and walk away tanjiro stares at genya then.smiles, eh knows genya has a tiny crush on you, one day genya was tough enough to speak to you. For once
