(This VERY long review below shows very, very mild spoilers and story insinuations that shouldn't matter.)
However, this manga is beyond being simple. What will have people become addicted to reading chapter to chapter will also be the reason people might drop this title: it's not the easiest read. Many manga use the quality of their art through good characterization and expression so you can understand feelings and tones without thinking. This title does quite the opposite which makes each panel so intriguing to delve deeply into.
Let's talk the story. Five people in a school setting living their everyday lives. Completely normal of a plot. Now throw in each of them having a distinctive power that gives some sort of a vague hint about a person. The power of a hand-sign which, upon thinking, *might* explain how they are feeling. A power which shows card symbols to represent an emotion and it's size. The ability to see someone's heartbeat speed. It's your typical silly power ability introduced like other stories but gives the author an immaculate way of making the most complex and obtuse characters out of any other story. Nothing is simple.
People aren't simple.
That should be the motto of this manga, where you can see the expressed hint of a person and need to think very hard on what that could imply. Seeing that a person is sad does not explain the reasons of why and how they are thinking about that. The stillness or quick beating of someone's heart in itself doesn't explain the full story. Just being able to see if someone is having a positive or negative feeling in their heart doesn't necessarily translate to a good or bad thing. This dilemma is the core story and what both the characters and you (the reader) are going to have to struggle with as the story unravels of five people trying to understand one another along with understanding themselves. I can't express enough how this plot allows the author to make characters in such a unique way to where the oddity of how they think and feel can be done without being lost on a reader completely. The mere fact alone makes rereading from the start have such different context.
The story evolves with an arc of each of the five characters, beginning with explaining what their special way of seeing how another person feels is as a power. With it, a not-so-blunt perspective is shown by this person on their personal concerns due to such a power and mainly relating to the main cast. It normally relates to romance, sure, where a very complicated person struggles to understand other complicated characters and possibly grows misconceptions just from misunderstanding what their powers are telling them. We get ideas from the representation of these powers and then a deeper understanding of how these people think and feel when the story decides to go by the POV of the next character down the line. It's so interesting, especially when you consider previous chapters you've read and now understand why a certain person acts or says what they say. Learning about another character and going some chapters back to see within another's POV gives so much new context and gives you more clues on what these people are truly thinking, feeling, and changing as time develops. The mystery actually has signs and small details which makes the manga so choked to the brim with personality and concepts.
The only things that might make people not enjoy the read is how difficult it is to understand these characters since that's the entire premise of the manga. As well, there is a certain pacing that is present to make the story work. You'll be following a character for a few consecutive chapters before it moves on to the next one. Some characters, by this POV, sort of never get the attention they previously did by a different arc and fade to the wayside till they are relevant again, so there will be times where you might not see a lot of a person. This is especially true for the VERY first character introduced: Kyou Ootsuka; this person will kick off the manga in the beginning and lay out the basics of the plot and drift off to the background while the rest are delved into. It's understandable as to why, but also a shame as others get a grand amount of characterization by comparison while his can feel more simple and less fleshed out; due to that, his current role in the story as well as him as a character feels pretty lackluster and sometimes irritating with how little agency or independent actions to the other four he expresses and wanes from either too shy or possibly too self-centered. Perhaps this will change as the manga finishes going over each person, so far covering four of the five at the time I've read, we can take a deeper look at the characters that deserve more writing. Keep a close eye on this manga. It's a great read.
The story and characters are the main great thing here, but the rest is good. Writing and way people speak doesn't hold your hand and all of the above said is complimented by rough line sketchings that also offer pretty great character designs and look. Highly recommend especially if you are looking for a romance/drama/mystery neatly and evenly package into one tale.
