The concept of living in a stranger's body after death, taking actions against their hardships, and reuniting with someone yes. School setting is also a similarity. Otherwise less so.
I'd say the stories have similar premise but this one is much more mild and healing compared to 'at the end of th road'. ML is not twisted in the head, he is loving and caring, MC is not being repeatedly bullied and assaulted (though the original owner of the body was). And the negative situations are resolved quicker than they could escalate.
I feel like this story is more focused on sadness and regret of both the ML and MC whose previous life ended quickly, and about the original owner of the body whom they feel bad for.
Is this story like ‘at the end of the road’!?
