Garfiel:  His heart had been strung out badly by the fact that she had covered for him and taken such a life-threatening wound for his sake. Why had she done that? What let her do something like that? Even though she was so upset at her brothers for risking their lives to protect her, why had she risked her life like that for Garfiel, who she had only known for a few days? Even though he had not thanked her for what she had done or expressed any gratitude for her saving him.

Mimi:  "Because Mimi fell in love with you, so it couldn’t be helped. It’s embarrassing."

Garfiel:  "—Ngh! What are you talkin’ ’bout after only a few days?" Garfiel clenched his teeth at Mimi’s embarrassing response.

Garfiel:  It had just been a few days. It was far too short of a time for feelings like that to develop and become this strong. It had been almost ten years that his feelings for Ram had grown—an attachment that lasted more than half his life. He had spent all that time with only that one girl reflecting in his eyes. And even after all that time, he had never once thought of giving up on her. That was how much he cared about her, doing and saying everything he could for her. So he couldn’t understand how a girl who was loved by her brothers enough that they would risk their lives to protect her could think to use her life for his sake after just a few days.

Mimi:  "A long time ago, Roshi said it! The requirements for a couple!"

Garfiel:  “…Wait, wha—?” It was an unfamiliar word to Garfiel.

Mimi:  Mimi leaped gracefully down from his shoulder. Turning around right in front of him, she held all her fingers out toward Garfiel. "A couple are always together, for years, decades, even centuries, right?"
gpt
Garfiel:  "There aren’t any that last centuries…"
human
Mimi:  "If feelings are forever, then a century is nothing! And they’re always together, but they still get in arguments, or fight over food, or stuff like that, right?"
gpt
Mimi:  "So Roshi said to pick someone you can enjoy all those arguments and fights with. Also, Roshi said you can tell someone who would be a really good partner because there’s an electric shock the moment you see them!"

Garfiel:  "A shock the moment you see them…"

Mimi:  "When Mimi saw you, she got that feeling and could tell we would be good like that! So a few days or a few hundred years is just a rounding error! Just an advance on what’s to come! Like Mimi learned from the lady! The vig’s ten percent!" Mimi puffed out her chest with a smile as Garfiel heaved a sigh.
human
Garfiel:  He was dumbfounded and taken aback. He had no idea what she was talking about. Does she mean an advance on a couple centuries’ worth of bond with someone who is going to couple up with you?
