습관

Seup gwan

Habit

When talking about something you regularly do, you can describe it as a 습관. For example: "늦게 먹는 것이 습관이 됐어요 (Neutge muk neun geoti seup gwan ee dwaesseo yo)". This translates to: "Eating late has become a habit".

What are some of your 습관?

With all the amazing webtoons-based dramas that have been released in the past couple of years, we have only become more excited about upcoming K-Dramas linked with webtoons.

The webtoon "The Mermaid I Loved" is a special case because the story was first written as a script for a drama production. The drama production is on its way and the webtoon was pre-released. The drama's production company, Group Eight, thought that in releasing it first as a webtoon they could showcase some of the various deep sea adventures of the story and also help garner attention for the drama.

The romance fantasy adventure webtoon “The Mermaid I Loved” ("내가 사랑한 물고기," literal translation, “The Fish I Loved”), written by Cosmic Bom Bom and Bubal (우주봄봄 and 부발), tells the story of a man whose intermittent transformations into a mermaid become increasingly uncontrollable as he experiences the emotion of love and spends time with a woman who he finds himself more and more attracted to. The season 1 of the webtoon ended on March 13th with 31 episodes.

Given the webtoon’s popularity, Group Eight is looking forward the positive effect the webtoon will have on the upcoming drama’s viewership. They have built a solid portfolio with dramas based on webtoons like "Taxi Driver", "My ID is Gangnam Beauty" and "A Good Day To Be A Dog". Among their awaited projects is the reboot of the popular drama "Princess Hours" (2006).

Currently, there are no actors cast for “The Mermaid I Loved”. Fans of the webtoon are waiting for the announcement of the cast. We can already think of actors and actresses who would be perfect for the roles!

We at Kpopmap have thought up a cast of actors who would suit this drama amazingly.

1. Sim Kai (심카이), a mermaid and 3rd generation chaebol

Sim Kai is the lead male character. He discovered he was a mermaid 12 years ago and he pretends to be a human.

When he shares physical touch with a woman, his fish scales begin to appear and he transforms back into his mermaid form. Because of this, he avoids all contact with women and has been single his whole life.

But due to his handsome looks, he has a lot of girls chasing after him, so he hired YaNa to pretend to be his girlfriend. However, he can’t help himself from having physical contact with YaNa even if it means he won’t be able breathe.

Kai is the son of the jewelry brand Inoroo, or 3rd generation chaebol, but he is not interested in the family business and instead prefers performing as a mermaid at the aquarium.

The actor must possess features suitable for long hair and a muscular physique to be able to portray a mermaid. He should exude charm and look dazzling in a suit, while also being capable of conveying a mix of cynicism, cuteness, and panic in his expressions. Comfort with underwater filming is also mandatory.

Moon SangMin, WEi's Kim YoHan, Baek SungChul, Kim MyungSoo (INFINITE's L), and Chae JongHyeop could be a good match.

Not only would they look stunning with long hair and looks amazing in suits, but their facial features would perfectly match the character's. Beyond their physical attributes, all five actors possess the talent and ability to convey Kai through the right facial expressions. The genre of fantasy romance suits them impeccably. Each actor would bring their unique colors and charms to the character, making him stand out on screen. Additionally, we can anticipate excellent chemistry with the lead actress.

2. Jung YaNa (정야나), an easy-going part-time student

Jung YaNa (24 years old) is the lead female character. She is a student who works a part-time job and has an easy-going personality.

She accidentally kisses Kai when she meets him for the first time, and shocked to see him suddenly fall very sick, she calls the ambulance. She ends up more shocked when she sees him put his face into a dirty bucket of water used for cleaning.

The actress should possess a mix of cuteness and strength, capable of expressing a wide range of emotions, and especially comedy. The character experiences rapid and extreme changes in emotions, so the actress should be able to show these transitions convincingly. Additionally, she should look just like a regular student, but be able to become a stunning lady with expensive clothes.

Kang MinAh, WJSN's Bona (Kim JiYeon), Chae SooBin, Girl's Day's HyeRi, and Seor InA could be a good match.

All five actresses have demonstrated their talented acting and are well-suited for a character like YaNa. Each of them possesses the ability to portray the youthful, cute, and fiery vibes of the female lead character. Comedy and expressive acting would not be an issue for any of them, so it would be a smooth portrayal of the character without overdoing it and making viewers laugh. No need to mention that they would all bring great chemistry with the lead actor! Being a romance, it is crucial.
