Each drama has a complex plot that intertwines the past and future. The time travel method varies though. Someday uses music and mind transfer between doppelgängers, while Meet Me uses a specific time and merged spaces. There’s the fun of a developing romance between leads, but also the mystery of whether actions in the past really can change/prevent events in the future. If you’re not afraid of having your heartstrings pulled, then go ahead. Also, both have a killer soundtrack.

Both dramas involve image change. In Tadashii Ouji no Tsukurikata, a group of girls tries to transform the boys in their class into popular "princes". They call their project Ouji Producer (Prince Producer). Similarly, in Nobuta Wo Produce, two boys decided to turn a gloomy female classmate into a popular girl. Tadashii Ouji is more over the top and anime-like than Nobuta, and Nobuta has more character and plot depth. However, if you like one drama, you may like the other.

Both have the same Robin Hood-esque, team of thieves vibe. Great music, story, and expressive actors.

The leads both possess a hidden personality, covering a goofy front with a passion for education. Both dramas deal with the school setting, bad teachers, bullying, and family drama. Both leads are eccentric, charismatic men with a penchant for taking unpredictable actions. If you liked GTO, I highly recommend Kazoku Game.

The drama-version of The Myth has a lot in common with Ultra Reinforcement. Both star Chinese Paladin actors (Hu Ge and Wallace Huo, respectively). The premise is similar. A modern guy stumbles into the past and changes things around him by bringing knowledge of the future, similar to Connecticut Yankee in King Arthur's Court by Mark Twain. But while Ultra Reinforcement stays a parody, The Myth builds an epic-long story and keeps the lead in the past for a lot longer. Unlike Ultra Reinforcement, the character in the Myth ends up being changed by the time period. Also, there's that whole switching back and forth between the lead and the people in the future trying to figure out where he went. If you're intrigued, try it out.

It actually is very similar to another enjoyable parody Royal Treasure with Luo Show, Huang Bo, Sun Hong Lei, Zhang Xi Ying, Huang Lei, Wang Xun, and Zhao Zanilla. I've never seen Running Man, but I imagine it's a lot like it but in a historical setting. The element of parody is intense. You have to treat it like a comedy, and then be surprised by the more touching moments. Royal Treasure's end is more heartfelt though.

SHARK is all about a band coming together and making a comeback after the death of the lead vocalist. The main character is another vocalist, like Eugene, that needs to step in. However, in SHARK, the focus is how the bad-tempered "God-sent" vocalist learns to get along with the rest of the band and helps them Keep Walking forward to achieve their dreams. If you liked Mr. Idol, definitely check it out.

Minor Spoilers: SHARK's ending is a bit sad but beautiful. Also, the sequel just derails everything, mostly.

Both have an element of mystery and tell an engaging story through the use of two different but interrelated time periods.

Both thrive on the adventure of ancient artifacts and brotherly relationships.

At first, it seems like the shows have little in common. The Myth is a time traveling-adventure-comedy drama and Nirvana in Fire is a historical-political-war-revenge drama plot. Although both portrayed by Hu Ge, the respective leads appear very different, Yi Xiao Chuan (The Myth) is a childish troublemaker from modern-day with a penchant for womanizing, while Mei Chang Su/Su Zhe (Nirvana in Fire) is the mature, elegant gentleman strategist. At first, I thought the Myth was only a time-traveling Hu Ge comedy that didn't take itself too seriously. Then, Yi Xiao Chuan's character started to change. As Xiao Chuan's role in the drama changes and he starts to be involved in the court and the battlefield, the drama becomes a lot more like Nirvana in Fire. There's political intrigue, battles, strategy, and inventive plots. I'm at episode 38 right now and just raised my score from a 7.0 to an 8.5. If you liked Hu Ge in Nirvana in Fire, give The Myth a gracious chance. You may be surprised.
