Gradual development of chemistry between MC and ML. Not rushed, no bland characters. Sweet, fluff and interesting. NO LOVE TRIANGLES. Like really fed up of plots were FL catches attention of ML and without rhyme or reason he is attracted to FL INSTANTLY.

 Basically typical rebirth/transmigrated  type of protagonist betrayed by her lover and stepped upon by her half sisters seeking out for revenge and catching the attention of 7th or 9th cold aloof general like prince are filtered out from this list. Like the thing is 'revenge' is more in light than romance part which is rather bland.
