I like to call this the Death Note of school romantic comedies. If Death Note ever made you laugh out loud (on purpose).
This manga is a breath of fresh air, as usually romcom manga start out with them meeting and being put into an awkward more than friends but less than lovers scenario, or some misunderstanding happens and all the characters are pissed at each other. Not with Kaguya Wants to be Confessed To, in this manga both main characters are too proud and scared to confess, so they try and bait each other into revealing their feelings.
There are a lot of absurd convoluted situations, AHA, THAT WAS MY PLAN THE ENTIRE TIME moments, and an adorable and goofy side character that may or may not be masterminding everything behind the scenes.
The art sytle is more suited for subtle humor than pure quality, and honestly it works a lot better that way.
The humor is intelligent and original, there are no cliche scenes (unless one of the MCs planned it out to be a cliche to get a reaction out of the other MC), only one Tsukomimi scene, and very little "hurr durr panties and boobies" humor. Its just originally funny.
Oh yeah, there's a minimum amount of ecchi fanservice in this. This is a manga that I could and did read on my phone in a Panera. This is probably because it is a shounen written by a woman, and that also makes it so that its an easily accessible manga for both genders.
