Boku, Unmei no Hito desu (2017)

Both have marriage as the end goal. Also Yamapi stars in both :)

if you love the chemistry between Yuki and Kara in Siren, you absolutely need to watch Boku Unmei no HIto Desu. yes, the genres of both this shows are totally not related but you can see another types of characters played by Nanao and Kimura Fumino. I would like to see both of them on another shows again without complaint.

They're both slice-of-life in a way, but contain quirky humor and relationships that go from passive love/hate to the characters being on the verge of marriage. The main characters also tend to go outside of their comfort zone in order to grow as people or accomplish tasks.

Marriage, or the benefits of marriage, is the main goal for the plot of each drama; granted, it's approached by the leads in different ways. Both dramas also contain quirky humor, fantastic supporting characters (and family members), and a sweetly developed romance (though frustrating at times).

If you loved Kimura Fumino's role in this drama You should watch Ito Kun, It's her best work in my opinion. Watch the drama first, then the movie ( Ito Kun)

same male lead teehee love, romantic however i recommend Unmei because I want to show you what a good/realistic drama should be. Second-Love is unacceptable for me so i give you a better alternative.

Written by the same screenwriter, they both share an well-paced, well-written script with incredibly witty dialog, lovable average-yet-quirky characters, and a delightfully awkward romance that blooms into something rather adorable.

Similar mains' characters the bro/sismance between the male group and female group similar vibe so I am sure you will like the Boku unmei no hito desu if you like Love Revolution difference is that boku unmei no hito romance is more of office romance

in both drama there is the actor Yama P. Also in both drama there is a "god" who will help the love story between the protagonists.
