I'm like 5 minutes in, not even out of the hospital and maybe it's just me, but the MC is kinda annoying. It's like, I get that it would be really stressful and disorientating to suddenly lose your memories and not know what the hell is going on, but this guy literally remembers everything but his family yet he acts really whiny/moody and entitled.
And more so, on the subject of family, he's acting really stupidly regarding them. Instead of being like, they're my parents/wife/sisters/daughters etc... and while I may may not remember them, I know that they know me and love me and as such they would be the best people to get to know again first as they can help me remember who I am and hopefully get back to my life, but this MC is just like nah, fuck them, I don't care about them, how about starting a new life and leaving them all to suffer? Hell yeah!
Idk, again, maybe it's just me, but the MC so far is just a bit of a douche bag. I'll keep going and see how it plays out, but I'm iffy so far.
