Ten-year-old Celine Mars dreams of becoming a great knight escort just like her father. She’s set to serve under Damien Willow, the heir of a powerful Duke. There’s only one problem—he’s a total weakling, or so she thinks. Celine vows to train the poor, defenseless Damien to stand up for himself, completely unaware of his real strength. Meanwhile, Damien instantly takes a liking to Celine, finding her cluelessness and pure intentions both amusing and endearing. When will Celine finally realize she’s got the wrong idea about Damien?

(Time of writing: dropped, chapter 31) It's so utterly boring even amongst other webtoon of the same genre. The trope of the male lead being a lowkey yandere while the fl is oblivious is pretty hit or miss in general, but this one is just bland. The characters have the personality of plain white toast. I feel like I've read enough to give it a chance, but nothing interesting happen.
tldr: just read something else
