Bokuben: we never learn manga ending

[UnitedVEXX]

I just finished watching and am about 3 quarters finished with the manga and After reading about how each girl has there own ending. I tried finding which volume has each girls endings but for the life of me I couldnt find anything. If anyone is able to list each which volume of the manga hold a girls ending I would Appreciate that
