Wait why is the helping them get out of the ropes I’m so confused

OMG!!! That is my thought too. Undine can easily weather away the ropes fibre by fibre! I bet the author is going to explain it away as not having enough mana. In which case, why is the fecking prince just sitting still n not removing the ropes for the girls!!! :/ this manga is an exercise is stupid n forceful trying to be a kid by a 27 year old!!! :/
