Ichika Kaneki:
i wanted to watch legends for a long time because i thought it was one of those dramas which have strong cool FL and Soft cute ml pairing. kinda sad to know she wouldn't be powerful majority of the drama
Yes, unfortunately if you went into it expecting the FL to be at full power and for the ML to be soft and weak for the whole drama you'd be disappointed, but it's a little bit more complicated than the FL not being powerful for the majority of the drama. Like I mentioned, the FL starts out very powerful, loses her powers completely for a relatively short period of time, and then her power fluctuates widely - sometimes getting pretty much all the way up to her original peak power level / enough to take on an entire enemy sect with the ML (power couple moment). Also, although the ML becomes more powerful than the FL and is ruthless when it comes to taking revenge for her death / protecting her legacy, he is always deferential to the FL (except when he is not aware of her identity). Now that you know what to expect, I'd definitely recommend giving it a try even though it doesn't match your criteria exactly.
