Hachiman Hikigaya — memorable quote from Yahari Ore no Seishun Love Come wa Machigatteiru.

“If you take someone at puberty, a teen... introduce him or her to a member of the opposite sex around the same age and say, "This is the person who was meant for you"... and then go on to spend a lot of time together... why wouldn't you fall for them?”

“A romance won't keep itself going forever. Eventually, you lose that all-important spark. Love has to be nurtured if it's going to last. If you want to be with someone forever, you need to put effort into the relationship... Great, now I'm talking cliches.”

“He may seem cold-blooded, but he's more human and his heart is more brittle than anyone else... so much so that if you filled it with human love or betrayal, it'd break easily... which is why I think he chose to avoid it all from the start: to love humanity. Do you understand? Not to accept it, not to face it, but he chose to avoid it.”

“People don't fall in love based on looks. And that's a scientific fact.”

“Love is more afraid of change than destruction.”
