Not bad, not bad at all. I've read all the chapters in only an hour! It is really nice actually! Thanks for translating!
The MC having the experience of 10 years of fighting and survival does make a huge difference. Him coming back is interesting. Knowing, that the future is already changed, makes it more interesting! Hopefully his friend and the girl with the sister will continue to survive, I like them the most.
His friend's a real bro and the little girl is great!
