Eri-chan is very honest with her feelings, so if she is kind and gracious to you, you're not presuming too much.

[It was one of her best traits, really. Sukuna beamed happily at making Okakou laugh, even if it was just a little. The sound was like being bathed in warm sunshine. The thought of his apprentice as a mother made him gasp out loud, eyes widening with happiness.]

Oka-chan you would make a great mom! And if there were little Oka-chans running around... Ah... I'd have to spoil all of them.

[It was definitely a pure and cute image, and he was sure Oka-chan's children would be more adorable and far better behaved than most of Muchi's brood.]
