"Hey! I'm Emma ^.^
I have a dare for you... you have to make/ but a flower crown and wear it for a whole week :D"

Yaku wasn't going into some girl shop to buy a flower crown. He wouldn't be caught dead. Instead, he bout flowers under the pretense that they were for a confession. When he got home on the day before school, he spent hours figuring out how to make the flower crown. After completing his crown, he fell asleep, exhausted.
The next morning, as he walked into school, he revived many stares, but no comments. Until Lev spotted him. "Yaku~~~, that flower crown makes you look 3 times cuter than normal!!" Unamused Yaku replied, "3 times 0 is still zero dumba**." Lev continued to follow Yaku to class, until the bell ring, indicating he was late to class.
Once Kenma and Kuroo got a look at him, Kuroo just came up and cooed at Yaku, "What a pretty crown for a pretty boy~" That one earned him a bruise on the arm. Kenma just nodded at Yaku, a little confused, but unfazed.
During practice, the flower crown was difficult to keep on, and prevent from not getting destroyed. Yamamoto even stole it for a bit, claiming he was a prince right before getting smacked in the arm by Yaku.
The next day, he needed to make another flower crown, he was too active during volleyball to not ruin it. The lady was happy to see him but another set of flowers the next day. The next few days stayed the same, except for the flower lady. She got increasingly happier after each buy, and Yaku kept thinking how lonely it must be running a flower shop in the city.
After the dare ended, Yaku continued to buy from her every morning and gave flower crowns to kids he came by on the streets. Kenma sometimes helped after learning of Yaku's routine, and soon Kuroo caught on too. The lady didn't seem as lonely now.

A/N: I didn't know it was gonna turn out this way when I started writing, but damn
