Another Day of School

Rin Kagamine and Miku Hatsune - The two have been friends for as long as they can remember, but when Rin realizes she has feelings for her best friend, she doesn't know how to deal with it and causes her to be in denial of her feelings. It's not much different with Miku, as she's been pining after Rin since middle school, and has also been hiding her mental struggles from everyone except her younger brother Kaito.
