Seems to me it's "Why wouldn't you want a hot Elven Waifu?" most likely.

Presumably answering a question about why that particular elf does the things she does in Dungeon Meshi, since unifying the race's lifespans is her goal

This is why he’s not getting the elf girls.

He made some mental gymnastics to justify why this won’t happen in reality.

Something something … incel culture …

I’m laughing at the idea that this person believes (or wants to believe ) that :

after he will be with the elf girl then, after he will die, the elf girl need to mourn after him for hundreds of years …

Like some kind of delusion that he is sooo good, and no other man can raise to this level, that will justify the hundreds years mourning.

Narcissistic fuck!
