Help finding the name of this isekai manhwa about a boy and a mysterious hooded god

I might be getting it mixed up with other genres honestly but I think it might've been an isekai where an entire class was transported to a fantasy world. The MC wanted to go home so the system spawned him in a demon forest area (?) as a punishment while everyone else got to go to a magic academy to learn. The MC then almost died but met a mysterious god character that looked kinda small and had a hood, and the god gave him some type of power (i forgot) and started following him around?

Other random details:

There was a huge conflict between the elves and humans and I remember the humans taking elves as slaves.

One character was a chuunibyou who wanted to get a harem, join the adventurer's guild, etc, so he left the magic academy to live on his own but failed to do so.
