You get similar feelings watching these two. Especially because same actor plays in both of them and the role he plays is kind of the same.

Writing things in a notebook and becoming reality is happening in both dramas.
Also, SF characters are in both of them.

If you like this kind of dramas, then this 2 are really similar. Both are about family issues, love, health problems and they're also funny. Even the length is pretty similar, but they're worth watching. You'll see the same inheritance problems, arranged marriage, love triangle, the rich guy and the poor guy, hidden relationship and more

Having Yeo Woo Jin as a lead made me remember about Ordinary Love, where I first encounter Woo Jin's appearance. Somehow, episodes 14-15 of Introverted Boss was similar to entire story of Ordinary Love. Falling in love with someone you can't be together due to family issues..

Same genre, different stories. While in High School: Love On an angel is living with the male lead, in Let's Fight, Ghost, obvious, there's a ghost living with the male lead. Both male leads are alike in some aspects...

Quite same plot, but the action is different. Maybe because I'll Die Soon is about a middle-aged man that want to live every day like is the last one, while My Friend Is Still Alive is about a high school kid that wants to die without regrets.

I'm not suggesting these two because they're similar. Not at all. The plot is completely different. But it gives you the same vibe. What I find it similar is that the main actress is a single mom with one kid. They are both funny and worth watching.

When I watched Go Ho's Starry Night, I thought there are some similarities with Her Lovely Heels. But I think if you're into stories that involve a love triangle between a woman, her new guy and her ex-boyfriend I think you should watch Discovery of Romance and Go Ho's Starry Night.

Two movies that involve children without parents, abused and used. In both movies there is a person that tries to protect them.

These two both reminded me of Resident Evil. They're pretty similar and though Train to Busan is pretty popular, I suggest you to watch Live Shock too.

these 2 dramas have some similarities. the villain is a spoiled chaebol's son who's the president of a big company. they have issues with anger management and no matter how much evidence the cops have against them, they come clear due to their connections.

No one related these 2? I felt pain watching them both. .... and the ending is awful in both
