"Thank you, Eren. I… I don't know what else to say."
Agatha hugged Eren while the potion vials and scroll were still between them. Those items were getting in the way. So she released her grip and stored all those items in her storage before hugging her guild master once again.
For quite some time now, Agatha had been stuck in the solid stage of the Novice rank. She wanted to remind Eren of his promise. She noticed, however, that he was extremely busy with his plans. So she had decided to hold until the guild started running its basic operation.
Eren fulfilling his promise to her without her reminding him of the same came as a shock to her. She couldn't help getting emotional over the fact that she won't have to worry about getting anthrope-specific techniques anymore. Her path to higher ranks had just been paved by her master.
"No need to thank me."
