Unfortunately there so many missing pages from this webtoon i personally decided to buy it on tappy toons!
But she did get kidnapped like that how it's shown ):
How’d she get kidnapped with her dad and brother in the house?
Okay so you know the gloves she gave to the red hair?
Well it has a blonde strand of her hair and so I guess he was able to reach her and took her when no one in her room protecting her while she is sleeping plus the window right there
OOooo, that's a good guess... that would explain the next chapter (⊙…⊙ ) *cough cough* (￣∇￣") I may have cheated but I was just so scared for her I couldn't control my mouse!! Even though I saw the pictures, I still technically have no idea what was going on since I have no idea how to read Spanish... soo... *couch*
SPANISH?! Where???
Another person down there vvv, posted it as well... but all I did was skim just to make sure she if she came out ok...

Wait... how did they kidnap her? Hard to believe they were able to do it while she was in the manor. Not to mention it was her birthday party, there should be so many eyes on her and around the place...
