Both of these have a very similar feel and style, more than a little dark and serious at times, while delving into issues of friendship, love, relationships. If you liked the Nana anime or manga but didn't really like the movie adaptation, give Last Friends a try.

It's another slightly dark film about a boy getting involved with a mysterious boy he knows nothing about and does dramatic things for.

Thai high school BL with virtually all the same character-types in this movie, but it's spread out into an entire series. If you rated this movie anything higher than a 5, you'll definitely love Make It Right.

Both protagonists are arrested and sent to prison for crimes they supposedly didn't commit.

These dramas both explore the uncommon drama territory of social-phobic chaebols who have a bossy, fiery team member that tests their boundaries as well as a competitive, ambitious male frenemy in their company. Similar plot devices and characters, yet differing execution so you can watch both without experiencing to much deja vu.

the main lead has never been kissed and meets someone/something that grants her the ability to to kiss good-looking guys of her choosing; also a short watch

Both are excellent crime/investigation jdramas and both have Kimura Fumino as female lead.
Siren focuses more on the romance, the case is good and twisted. Ishi no Mayu has no romance but darker even more twisted cases.
both recommended

Similar threads of past lives, honour, after-life, ancestry and culture

Both leaders are members from Arashi band, both of them got into an accident and became paralyzed.

Thai Drama always have great message, great acting, especially former GTH Production House, the former have a good acting and chemistry

Both are crime series & though the story might not related at all, it gives you the same feels: goosebumps & keeps you sit on the edge of your seat since it's full of suspense & unpredictable twist and turn. You won't regret watching this, it truly is a masterpiece.

both leads are similar in their emotionless work mode but in haken no hinkaku the lead is more expressive in her off hours.

they both are hard working women ready to tell it like it is when the time comes.

There mostly the same thing but its just the modern and ancient time difference

Though they might be a bit different, Blood is still a medical drama which I have enjoyed as much as this one. You should totally give this a try, you will never regret it :D
