stop letting 'strong' confuse you. It's just put there to differentiate from the normalcy of poorly written female characters. A female character who is physically strong can be 'weak' if that's her only defining trait.
A woman isn't a thing to catch because she is pretty to look at. Glorifying "hard to get" perpetuates rape culture that tells men it's okay to keep pursuing a woman after she says no because she doesn't really mean it. She's just "playing hard to get".
