HELP! YAOI MANGA

I cant remember that much but it has:

- Senpai x Kohai relationship
- Both are members of Baseball Club
- Senpai is really good at baseball and kohai is only a 1st year
- The art style is unique! (It doesnt follow perfect anatomy but it is still beautiful, imo)
- & I think the focus of the story is about their relationship which is in this case, a kohai x senpai relationship
- I remember the first scene was uhhmmm they were hiding in the club room something?

I hope someone can help me even thou the description is not that clear! I'm sorry for the inconvenience ToT

THANK YOU!!!!! ヾ(☆▽☆)
