I'm looking for some manga/manhwa, where a prestige female lead help male lead to grow strong.

• Long hair beautiful female lead please, this is a must     😛     
  

• their relationship should be bad from the beginning, rivals or enemies   >:-(     
  

• when female lead train male lead, she starts to fall for him   
  

• female lead should fall for male lead first  😲    
  

• it should take a while until she realizes her feeling for him, I don't want a rush romance  
  

• Male lead must accept female lead love, no one-side love plz  😉    
  

• there must be some fighting, better with some fantasy  
  

• female lead must be either cold, or very confident in herself  🤨  
  

Thanks in advance 😁
