Yeah but this is an otome isekai where nothing is off the table. It never really bothered the authors that its a little girl ending up with an adult. Also as I said there is nothing wrong with her doing things to get his attention. The problem starts if he reciprocates (like in I'm a child of this house)
After reading I'm A Child Of This House I have a slighhhtttt suspicion that the orange head girl has a crush on the knight dude. Nothings wrong with that, tittle girls can crush on older people BUT if they end up together I will be losing all my remaining hope in humanity
