Ai-Ren/Tear Jerker

"Why would you recommend this /a/? My eyes are like a broken faucet."

—an /a/non after reading Ai-Ren

Ai-Ren is perhaps one of the best manga to read if you want to finish with something in your eye. Or in your heart. It's that kind of story.

This is the story of a terminally ill teenage boy who gets an Ai-Ren - an artificial person designed to provide companionship for people with terminal diseases - who has an even shorter lifespan than he, and their love.
Chapter 40.5 has one:
- Today... let's sleep in a bit longer... ok?
  - This troper has registered just to say that this was the biggest tear jerker moment since the passing of his grandmother.
