Fair enough
Just know Stabby Mike doesn't die due to the bullet because he has the cross to protect him he fainted because he saw his own blood so your not 100% correct on that bit but yes the brainwashed part is true and I didn't know about the previous comment by Cari my mistake. However I feel like the harem ending being the true ending doesn't mean 100% we won't see the main character in eternum at a point because we don't know how many years Eternum is after Once In A Lifetime as far as I'm aware.
