It had been a while since you and Muichiro had hang out together as not just comrades but as eachothers significant others. You were bored so you had wanted to take care fo his hair, so currently you had him leaning his head back onto the tub, quielty humming along to a song that just came on from your phone, gently massaging his scalp with shampoo. He was just sitting there, his eyes closed. He was probably asleep, you noticed it was a habit of his to just fall asleep out of nowhere.
