Romance drama with bully/delinquent/scary looking male lead?

i love this trope too..
Kurosaki-kun no Iinari ni Nante Naranai- fantastic movie
diamond lover- idk whether u will like it
just you- the heroine appears to be kind of not scared by hero first but she is.. she falls in love with him first- wonderful drama
rich man poor woman- another osm drama
