When I first saw Tomorrow, it just had this odd sense of similarity to IOKTNBO.
First off, the female leads are headstrong. The supporting cast is just a fantastic group! I love each and everyone one of the character and the stories they had. Both had a theme closely related to suicide, mental health, and healing from these scars.

Both are based on historical events,taxi plays important role,both are very emotional n adventurous with deep characters.

In both series ..for the sake of pleasing the female lead..btge male lead likes to throw money at her..

The female lead is someone who loves money.. the male lead is someone who has them.. they co-habitate and have a relationship, based on contract.

It has a main lead, which is a very famous celebrity and a female lead,cwhich works many different angles to try to make her career good..but fails.
Both make leads are lonely and arrogant...

The male lead is both a photographer and has poor vision which then he travels with a girl for the last time.

The male lead is a Doctor in both dramas. Both are adapted from a novel. Friends to Lovers. Both live as neighbors.
