I like it. It's not action, action, action but more relaxing? It does have it but not to the extent one would maybe expect. I didn't mind it since it was still entertaining and funny. He's a likeable character and does have character development too imo.
I'm absolutely living for the moments where his past self shines through. It contrasts his calm, stoic demeanor so much to see his crazy grin with the red eyes. And that makes the action worthwhile?
He wants to live a normal life (which of course doesn't really work) so yes, that does include romance. Not that he's really into that for now. Can't see him with anyone yet either because he's a bit... awkward? Socially not adapted? But he definitely gets better I think.
The current potential FL is headstrong but I don't dislike her. Not harem either. It's just that you meet different people in your lifetime and if it doesn't work you move on. So there are multiple potential FLs but not parallel (thank god). He's not that type of protagonist anyway.
