"It was pretty fun, but Cecilia, how were you so good at it when it was your first time too?"
"Hm? It wasn't my first time. I played it once when I went out on a mission with Mister Chang'an last time."
"Oh? You played with him?"
"No, I played by myself."
"...What? By yourself? Then what was he doing?"
"He was dealing with the Honkai."
A look of utter shock appeared on Theresa's face as she stared incredulously at her close friend, Destiny's strongest Valkyrie.
"You went out with him to deal with the Honkai, but you were playing games while he handled everything alone?"
"Um, Theresa, please don't look at me like that. I didn't want it to be this way either, but he's just too capable. There was nothing I could do."
"I don't believe it. Cecilia, you're so strong—how could there be nothing you could do? I think you just wanted to slack off."
Theresa had meant it as a joke, but Cecilia took it seriously.
Then, during their next Honkai suppression mission, Cecilia brought Theresa along, and the two headmistresses slacked off together.
"Do you believe me now?"
"...Mm. We really could only slack off."
Theresa nodded with deep understanding and said she wanted more missions like that in the future.
Her past was much like Cecilia's. Both of them had been busy with missions and rarely experienced the outside world.
She submitted a request to Otto, only to be flatly rejected.
"Theresa, if you want to play, then enjoy yourself during your academy holidays. But don't disturb Mister Chang'an and Cecilia, understand?"
Theresa did not understand why, so Otto gave her a lesson on the harmful effects a third wheel had on a man and woman trying to develop feelings for each other.
