The first season of the drama Thumping Spike 2. The drama's main cast is different.

This drama is a Historical drama and it's also starring Lee Joon-gi as the 4th Prince Wang So.

Both are train themed shows that are rather lighthearted and both are by the same writer.

- Both high school dramas.
- SUFBB main characters are part of a rock band. SGG main characters are part of a cheerleading squad.
- Both have rivalry between two groups.
- Cute romance for main and side characters.

in both dramas, both female leads have to keep their identity a secret and both girls are surrounded by boys that they learn to cope with

Because both series have similars storyline, the confusion between a woman wear as man, a very good man trying to be king and fix the world. The difference is basic about the second characters, which are more kind and nice in Love in the moonlight than in Shine or Go Crazy.

These were like hand-in-hand productions. They are so similar that the ending is kinda obvious though..
-Manga adaptions
-Boy x Boy relationship
-Work-place Environment
-Sickeningly sweet
-Insecure Uke

Gen Urobuchi has stated that Black was a huge influence on Gaim - specifically, the duels between Black and Shadow Moon were what influenced the show's writing. Plus, Kouta is very similar to Kotaro, and Shadow Moon has a counterpart in this show as well (I cannot say who as that would spoil things).

I know it may not seem the same at first but if you look at the differences, you can see that they have the same feeling.
-BL theme
-Vampires
-Human giving blood to the Vampire to survive
-Open-ended

Both drama have male and female leads solving crimes and a smart, psychopath killer after one of the main leads. The female leads are both helping the male lead solve crimes. Also main leads in both dramas have special abilities (although it's on the supernatural side for The Girl Who Sees Scents).

The Girl Who Sees Scents is more focused on the female lead who I found much stronger and more interesting than in Love me if you dare, which is more centred around the male lead. The romance is much better and more consistent in The Girl Who Sees Scents.

Both of these dramas feature a similar mix of poignant political (mostly historically accurate) intrigue, life and death situations, and a passionate romance at its core. Therefore they give of a similar feel.

The grown up now and the younder adolescent, the friendships, the love, the fun...

It has the Reply 97 reminescing vibe, the feel, the energy, the happy and the fun times where things were good, when idol pictures were plastered on the walls, when love blossomed outdoors and not in front of a computer or a mobile phone screen....

The two drama show the struggle of a Crown Prince who has to deal with court intrigue.
The Crwon Prince/King has to deal with an "impossible" love in both case.

They are both historical dramas. Both love stories have a Romeo x Juliet vibe, Princess man is more serious, but both dramas are beautiful in their ways
