Introverted Boss

Both are dramas with healing stories, where the male protagonists are business heirs, who suffer from mental disorders/barriers . They have a high position in big companies and get involved in dark intrigues and secrets. But despite that, they manage to stay warm-hearted, and they care a lot for the people they love.
The female leads have similar personalities; both are optimistic and cheerful, but both experienced tragic events in the past. They help male leads to become stronger and to overcome their mental problems.

Both dramas center around an office romance where the participants are completely different people. The balance between work and private life begins to disappear and we get a view behind the main characters. Also we got humor and a bizarre boss in both dramas.

Both the leads (Male lead in Introverted Boss and female lead in Flower Boy Next Door ) are introverts! But the cheerful partners of theirs help them in regaining their social positions.

Quiet/shy MLs and energetic FLs that help them break out of their shells. Where Stars Land feels more slice of life, while Introverted Boss has more romcom vibes

There are many similarities. In short I think my shy boss is the light hearted and fluffy version of secret.

The female lead in secret reminds me of the male lead in shy boss. Without revealing too much they both made similar sacrifices.

The male lead in secret also reminds me of the female lead in shy boss where they both similarly fell in love with the other lead in the same way.

Sorry that it was really long and vague. I didn't want to spoil anything. But I both highly recommend both!

Both have a male lead that faces a trauma leading to him becoming more reserved. Through the help of the female lead, the male lead becomes more extroverted.

Both deal with Male Lead Characters who have difficulties expressing themselves and seem to be drawn to an overly expressive Female Lead Character. The way they meet is also similar: comedic (only) at the surface. Both Introverted Boss and Another Miss Oh's stories revolve around big misunderstandings.

They are both office romance dramas.

Leads do have some kind of a connection from the past in both dramas (even tho it's a different type of connection... hm... no spoilers~)

Both are light hearted and cute~

Female lead is that kind of cheerful, cute, a little annoying girl (I didn't like the female lead in Introverted boss but i liked the one in She was pretty)

The male leads... Well, they aren't really similar in any way i think but they still remind me of each other idk why XD

Both of these dramas are centered around a protagonist who is the boss or leader of a group but never shows his face, only for an incident to cause him to be suddenly forced to show his face to his fellow team members.

In both shows the leads are socially awkward outcasts. They also idolize their popular love interest.

They both focus on the CEO of a company and one of his employees.
He is the CEO (Xia Ke) of a game company, who is looking for love.
Xing Yu, who illustrates the games.
Over time these two are getting closer to each other.
