Birthday on the Beach (Tsukiyama fluff)

(This is my first story, so please don't be too harsh)
The Karasuno boy's volleyball team is doing a team bonding exercise where they spend the night on a beach. It happens to be Yamaguchi's birthday, so Tsukishima plans a surprise.
This is going to be teeth rottingly sweet with absolutly no smut. (Their relationship is so pure to me)
Disclaimer! I do not own any of these characters, all credit to the crestors of Haikyuu.
This cover is a screenshot from a webtoon #Muted. (It's amazing please go read it) This is a boyxboy so if you don't like it don't read this story. I also moved Yamaguchi's birthday to July 10th
All these characters will be ooc (out of character) and I a reminder that I update when I want, so there might be big intervals inbetween updates.
