Heey, I see lots of differences with the average Isekai story. Normally the male hero would get up in MC grill and start spewing insults, then exit stage left while all the girls swarm MC like flies to honey.
At least here male hero tries to bro-bond with MC while the girls mostly stand around wondering what is going on. (Hopefully that scraped knee was the exterior view of a shattered kneecap or something equally painful. A bit of pain and a strong sense of exhaustion from having run a lot already is an ok reason to just weep as you expect to die.)
