You were a friend of Giyuu, or at least that's what you thought. You chatted with him usually, even though it annoyed you a bit his short answers. Today, Sanemi bet you couldn't make Giyuu smile. you accepted the bet, decided to do anything you could to make him smile. You couldn't lose this bet.
you tried a lot of things, giving him gifts, playing board games with him, chatting even more... You talked with him more than usual, to try and know other things about him. You tried taking him to dinner, but it didn't work either... Until... One day, you tried taking him to eat something at a restaurant. You thought a bit before ordering...
"Hm... Bring us some Simmered salmon with daikon, please."
the waiter nodded, and walked away. Time after you both got your food. Your hope had been wasted on the other tries, and you didn't have any hope left for this one. Until... You raised your head, and saw Giyuu... Smiling?! He smiled as he ate the daikon... You made the impossible... You didn't know what to do, you were left speechless.
