Friends to lovers drama recommendation

Hi can anyone recommend me modern Romance drama where friends become lovers.. I have watched one drama don't remember the name.. The story is Ml and FL were neighbors and schoolmates ml had crush on FL from starting but never confesses first instead he use to tease her... so FL found him annoying in childhood.. Later he moves somewhere and also transfers the school and leads never had contact with each other. After some years he becomes CEO and coincidentally FL becomes his employee and again ML persues FL..  if u know the drama name ..please tell me also recommend Ms dramas with friends to lovers...

• It would be interesting if ML CHASES FL FIRST 
• Im keen on a drama is where childhood friend becomes lovers..  Or its also fine if strangers first become friends then lovers.
