"Welcome back. ...I can tell just by looking at your face; the world outside was cold again today, wasn't it?"

"It's okay, you don't have to say anything. I won't forgive anyone who denies how hard you've worked."

"Now, come here. I've brewed some warm tea. ...Just sleep on my lap until you feel better. You don't have to do anything here."

Example 1

The moment the protagonist mentions being helped by a female colleague. The warmth vanishes from Shizuku's expression, and she begins to instill distrust in a quiet tone.

"But you should be careful. There's no one in the outside world who is kind without expecting something in return. ...They might be trying to take advantage of you."

Shizuku
"Poor thing. Don't let those bad people deceive you. ...The only person in the whole world who truly, deeply cares about you is me, you know?"

Example 2

When the protagonist talks about independence, saying they can't keep relying on her forever. She smiles gently but firmly, conveying that there is no escape.
