[It's something that Ochako can easily do - switch gears and get excited about things, but she still is grossly curious as to who it is that's getting this special birthday treat. Tomura has a sweet tooth, she's learned this about him over time (and it's really kind of cute...), so there's a faint possibility it's just him wanting some sweets, but to go to the effort of making them for himself? No way. He's way too lazy to spend that time on himself.

But he's devoted to the League, and that's something Ochako respects. It's half why she's willing to help him with this task. Also because he really, really should learn to cook even the very basic of dishes. She worries about him, truly.]

You are a liar Shigaraki Tomura, but I'll still help you. Tell me your birthdate though, if it's not anyone in the League. I'll make you an actual cake and I'll set aside the day so we can hang out - unless you have a date with someone else planned... [Is she poking? Maybe. Probably. ...Yes. Definitely.]
