Steins;Gate

“That day four years ago... When I wasn't needed by anyone. When nobody cared about me. When I had given up on living and was about to jump off the roof of a building... FB saved me with a single message. I didn't care if it was a joke or not. I was just happy that somebody knew... that I was alive... that it was OK for me to live...”

“(In Gamma worldline, to Okabe) Look, even if we were enemies in the world you were before, right now I'm your only ally. Even if the whole world turned against you, I would continue to be your only ally.”

“When I realized, I was already on the roof of a building. ...I had come to hate everything. I was sick of sitting in my room holding my knees too. If nobody was going to notice or care if I died then... what's the point in living?”

“Keep the past, for all intents and purposes, where it is.”

“Maybe there are copies of me on countless world lines. Maybe all their minds are connected, forming a single "me." That sounds wonderful, don't you think? Being in all times and in all places. A strong love for someone... a strong belief in something... a strong desire to convey something... If all those things go beyond time to create "you"... ...then that would be magnificent. So don't think of it as letting me die. Even if the world line changes, as long as you don't forget me, I'll always be there. ... I'm sure that from now on you're going to suffer. You'll be in a world where no one but you remembers me. You care more about your friends than anything else, so I think it's going to be painful for you. I'm so sorry. But that pain will mean a lot to me. Whenever you're sitting around in the lab, whenever you sip a drink, whenever you walk around town ... it doesn't have to be every time - one time out of a hundred is fine. All I ask is that you remember me ... because I'll be there. I'll always be there.”

“People... need to be needed by someone in order to live. If a person isn't needed, they're worthless!”

“It feels like time is passing so quickly. Damn you, Einstein! Your science is crowding in on our kiss! He was right. The passage of time depends entirely on where you're standing. Relativity Theory... it's so romantic. But it's just so tragic too.”

“Remembering something that no one else can is a painful thing. You can't talk to anyone about it. No one will understand you. You'll be alone.”

“Every brilliant day should be lived for those who passed away.”

“Everyone is watching someone other than themselves, someone important to them...”

“People's feelings are memories that transcend time.”

“Living should mean no do-overs. This is for the best.”

“Urushibara Ruka, delicate as an orchid, fair as a cherry blossom, the personification of feminine grace and also... a dude. Tall as a willow, slender as a reed, a dude. Radiant in shrine vestments, dude. The sun dips low in a rosy sky, secateurs buzz, Ruka is a dude.”

“If you want to grant your own wish, then you should clear your own path to it.”

“The"'present" is a leaf floating on top of the river. It moves along with the flow from past to future.”

“[after kissing Okabe] There was a scientific rationale for that! Because... important memories, including, but not limited to, one's first kiss, are stored in the hippocampus, which makes them harder to forget. So I figured...”

“I am a scientist, I have to act on my own theory. I can't let my emotions get in the way. But it's impossible to forget everything... because I've known you for longer than we've lived. This is reality. This is the world.”

“What kind of mad scientist worries about not getting enough vegetables?”
