Doma Residence, second floor.
Mashiro's generosity had already made Sogo Doma suspect that his useless little sister was definitely "up to something." At that moment, he gently pushed the workshop door open a crack, preparing to eavesdrop—cough, cough... to listen and see whether that dumpling had any follow-up plans. Even in a battle between siblings, one had to know oneself and one's enemy to emerge victorious every time!
As the saying went, "Heaven never mistreated those who came prepared!" The moment the door opened a sliver, voices reached Sogo Doma's ears.
"Umaru, Umaru-chan, if we really do this, Sogo-kun will get angry, won't he? You..." That was Utaha Kasumigaoka's voice. She seemed to be trying to dissuade the dumpling.
So there really was a conspiracy! Hearing this, Sogo Doma became even more certain of his suspicions. Still, he seemed to have misunderstood Utaha. She was a good person! Rather than joining that dumpling in her nonsense, she was trying to stop her—perhaps he could believe in the true, good, and beautiful side of human nature again...

Wait, if he wasn't being easygoing because he didn't want to make a fuss with this dumpling, didn't that make him a petty person? So which was better—being easygoing or petty?
"Umaru-chan, that's not right..." Utaha Kasumigaoka said softly. "Being easygoing is merely a form of tolerance. Because Umaru-chan is Sogo-kun's little sister, no matter what Umaru-chan does wrong, Sogo-kun can tolerate it
