wow... the escalation/twist of getting found out, and it's just chp 2, pretty rare otome isekai situation lol
Now I think about that, it should be quite easy to make mistakes and get suspected by family members because it's difficult to fake every little personal preferences and habits though, especially if there are clear signs particularly if there are those that involve involuntary reactions like allergies. Thus honestly IMHO, getting discovered very soon should have been more of a common thing in otome isekai...
