    Best Volume Thus Far, Hits Every Single Note Wonderfully
  

*by T***S on Reviewed in the United States on May 29, 2019*

Theory of Happiness followed the more traditional blueprint for these sorts of romance manga doing little to nothing to stretch its wings beyond the gentlest of softest of entries in the genre. That’s not a ding against it or anything as it’s a really wonderful entry in the ever-evolving relationship between Kohei and Taichi and their feelings without focusing on the more ethically concerning and unsettling aspects that some of the writers like to include in these manga.The introduction of Maya and her muddying the waters between our main characters helped rocket their relationship to a new level. A love confession that Kohei reiterates with Taichi after a really dramatic moment forces Taichi to deal with his feelings. And then Taichi getting a job offer finally gives him a chance to face character growth and some type of maturation with what he wants to do with his life. Together, these pieces of plot add several elements to the story that the first volume lacked, and all of that is with the backdrop of the ever-declining aspect of Kohei’s hearing and the continuing difficulty of those who are only hearing-impaired struggling to find their place in the world. Ultimately, this volume is my favorite of the ones I’ve read so far as it hits every single note that I love.I got the misunderstanding involvement, the blatant confession from Kohei delivered with sign language that just works its way into Taichi’s mind making him finally realize things, and the aspect of time away from one another resulting in Taichi just realizing how much he needs Kohei in his life. Really, this is just plain wonderful and easily one of my favorite Yaoi manga in ages. Like we even got both a hug and a kiss scene that I just love love love to death in these, like, it was enough to make me smile so big and brightly, lol.Overall, really awesome entry.

    Beautiful and Engaging Story
  

*by A***H on Reviewed in the United States on December 4, 2020*

I’m ecstatic about the arrival of this book. I read it online, but I loved the story so much that I needed to purchase a hard copy of it! The manga came in perfect condition, and the cover is absolutely beautiful.

    I can't wait for the third installment
  

*by I***O on Reviewed in the United States on June 3, 2018*

Okay so I just bought this one and the first one and I had heard there was going to be a third one before I bought them. I just want to say this is one of the best BL I have ever read. It's calmer, respects boundaries, and is wholesome. The BL isn't all up in our face, which I like a lot, and is shown more of the friendship in a relationship rather than dominance and sexual attraction. The characters I think are well written out as well as how their lives are. The back stories are pretty paced and so far has shown us the general story. I can't wait for the third installment. It's coming out around Christmas so I totally know what I'm going to be getting myself.
