similarities:
- They are a couple (secretly) very early and work in the same place.
- The ML has a scary reputation at his workplace as "the devil" but that doesn't take away from him the role of the hottest guy. (as hase who is known as the phantom)
- The FL is cheerful, motivated, helpful, funny, naive, kind .. and dedicated to her work.
- there's a slight age difference that is never mentioned, when she was in high school he was already a doctor.
- She comes from a modest background, and he comes from a wealthy family.
- A co-worker falls in love with the FL.
- it's adapted from a manga.
- It's a J-drama.

it's not the same atmosphere as Love is Phantom, the ML is not so gentle with the FL at least he wants to make himself look tough and cold in the beginning. But their romance gets cute. The FL is not as naive and has more personality than Momoko.
