"I made a cake and had it." Talk about a redundant statement. Just "I made a cake" is enough. It's presumed when you make food that you also eat it.
Or actually, because it's a birthday celebration just saying "I had cake." would be enough.
@Hcoregamer well she just seemed to blush. Probably people didn't pay attention, and if they did notice they just thought she wasn't well, she did have motions sickness after all.
@Madcat6204 I was confused too but Slut is a mistranslation, see X3h0n's post on page 4.
I guess the scanlators only changed it to the Lewd skill on the satus page, and not in the dialogue.
