Both the FL are similar in personality
Both have a love triangle
Both FL can fight
Both the ML are highly intelligent
Both ML are highly respected and have a high status
Both FL are smart
The stories are not super similar but at some moments it has similar vibes
Under the power is more about solving crimes and TMBFY is about the FL entering the martial word and about the different clans involved.
I would recommend both as they have a good romance and have a mainly good plot.
