I Just Happened To Fall For You

Man the novel does quite a lot of time travel barely understanding But love it

and concludes everything without enough evidence. It was as if they were deaf, no one could hear a word the MC said. The Demon King's past is very interesting but only fleeting and does not leave any impression. I'm sorry I'm using a translation tool so some of the words may be a bit confusing but you can still understand my general idea.
SCORE: 3/10
SUMMARY: DON'T READ IT BECAUSE IT'S JUST WASTE YOUR PRECIOUS TIME
