The Abandoned Hero is Going Home

The Abandoned Hero is Going Home summary:

I, Ogata Yuuto and my classmate Hijiri Youichi were suddenly summoned to a different world. Apparently, the summoner Lilia tried to summon a hero from another world to save hers, but there was only supposed to be one hero and Youichi was said to be the true hero. Then Lilia abandoned me in this world I knew nothing about. This sucks. I miss McDonald's, Coke and convenience store food. How do I get home!?
