Both of the drama are dealing with cleaning dead's belonging.
both lead are curious to find the truth, and both of them are absolutely kind

Fun, funny, enjoyable, some action, some fight scene. Comedy action movies. One of them was an agent with elite agent and now live like ordinary person. The situation force them to bring out their skill.

same group of hilarious, chaotic, talented boys
the same banter, arguments, Haechan screaming, Jaemin being a dad, Mark being Milk.... it's DREAM at their best :)

Both dramas have a couple that is meeting due to unusual circumstance again but where one of them makes the decision to help the other. By doing so all actors get involved in a case that challenges not only the relationship they have, but also the characters development too.
There are a lot more similarities between them however naming them would spoiler too much.
IF you enjoy one there is a high chance you will enjoy the other drama too.

Both were released nearly at the same time and both are absolutely gripping dramas that will leave you guessing on what happened and who is responsible for it.
Both have absolutely amazing cinematography and background ist, astonishing acting and interesting characters that are so diverse and complex.

The only difference is that while Burning Ice focuses on one specific case with multiple parties involved, Day and Night focuses more on a variety of cases.

Nonetheless there is a high chance that if you like one you will enjoy the other drama.

Both main couples have an older woman and a younger man that happen to meet each other after failed relationships. But what makes them resemble the most is the awesome chemistry between the pairs, although The rational life was a lot more focused on them, while the vacation of love gave more screentime to the other stories happening simultaneously

After a failed one-night stand, the bold woman secretly left, leaving behind a provocative message with a lipstick mark. The man, however, swore to find this woman. The next day, all the major media outlets released a ’Wanted’ notification at the same time. Tong Tian Ai was on her phone when she saw the notification, which made her face turn completely red. “Qin Jin Yang… the Qin Association President…“ Because of that lipstick mark, she had become the Chief Executive.

- same director and cast (joss and tay)
- they both have that messy, dirty and heavy atmosphere;complicated relationships etc.
- both have straight female-bisexual male-gay male leads

four best friends. the main couple's story from BT is similar to one of the couple from LY. the characters are similar. as in a hot tempered girl, the calm and mature kind, the doenst believe in love kind. but from what i've seen so far both are having different endings. BT have comedic tone to it while LY leans more to the mature plot.

if u liked LY then u should defenitely try BT. but if u liked BT for its lighter tone then LY might not work for you. i loved both dramas.

These two dramas are different but I think the female lead working her way up is similar and showing how her intelligence can be useful and just how they stand up for themselves is what connects the two and if you like one of these you’ll probably enjoy the other as well.

It is also story about a woman who struggles to survive in family, fighting with her wits, intelligence rather than with muscles. Also has a nice romance story, which is not in the frontline though.

Both depict a similar interspecies love trope in which a supernatural character and a human are forced to cohabit. The Angel and Alien are innocent and curious about what's around them. Then, the human main teach them about simple thing on Earth and customs.

This drama had even scene-by-scene references from TKEM. It seemed as though the writer/director took too much inspiration from TKEM. Anyhow, there is forbidden romance just like DAYS in TKEM where the main leads belong to different worlds. Also, there are in depth meanings for deity, death and balance. There's also fate which brings the main leads together. It's an awesome drama and I personally loved TKEM a lot more than DAYS.

Both are crime dramas where the leader of the investigation team is a woman. Both women are very smart and skilled to find the culprits of the cases they handle. Both women are challenged by the work and family situation.
Both give off a very similar feeling.

Both dramas revolve around a character who gets confronted with the death of a close family member. In both dramas the character seems to be the one behind that murder. Throughout the drama we learn what has happened. Both dramas have characters that have amnesia and slowly throughout the drama get their memories back.
Both are gripping crime dramas that will keep you on your seat.
