Anyone hating on the harem ending seems to have missed the fact that probably out of all harem protagonists Na Kang Lim is the one who is most deserving probably out of any character in the genre to have a harem end.
My man basically died and failed hundreds of thousands of times and had to endure the trauma of death and watching the heroines die in front of him and he didn't give up.
Dude's name should be changed Na Chad Thundercock. He 110% earned that Harem End and deserves to drown in all that waifu pussy. He would be worthy of a Green Lantern ring.
