A basic formula series that continues to drag along
(Read up to chapter 150) Nisekoi is as basic as a romantic comedy can come by. It has everything you would expect regarding cliches that have been seen throughout this genre, from the gullible main male character, to his love triangle between a Tsundere and a Shrinking Violet, to having a male comedic best friend, and so on. The one thing this series has going for it is the hilarious facial expressions seen amongst it's characters, and even that has been kinda lackluster as of late. Early on, the story of the Childhood Marriage Promise has a lot of time dedicated to it, and has a lot of readers invested as to who it was that Raku made the promise with, but it becomes very apparent that it was used as an excuse plot only to get you interested in this universes' setting. Once it's been established with all the characters in place, the series then turns into a formula series that mostly continues with one-off chapters containing overused Harem shenanigans seen throughout manga. Once in awhile, it returns to the Marriage Promise (Yui's introduction being the big one), and dedicates a chapter here-and-there to push forward the Shuu and Ruri shipping, but aside from that, the manga has continued to drag along with no end in sight. The anime adaptation is perhaps worth looking into though. It's not everyday you see a Rom-Com done by Shaft Studios, and actually gives the series a unique look compared to other shows from this genre.
