I suggest
aimer - stars in the rain
milet - tell me
Yorushika SUNNY
aimer - Rokutuseino no Yoru
aimer last stardust and also brave shine
rokudenashi - the voice
Haaaa~ first volume done. I feel like I rushed the romance a little, but as far as my first time writing, I think I did good! If you have any suggestions for songs you want Akira to use, or the group to perform, leave them in the comments!
