it trending that it gonna get movie , is it worth reading or should I wait for anime adapt...

I watched the anime and the movie (it's out now in Crunchyroll) and it made me want to read the manga so I'd say go for it (=・ω・=)

I readed the manga some time ago and now I watched the movie there’s some stuff that it’s on the manga that doesn’t appear on the movie If you wanna know more stuff about mafuyu and uenoyama and mafuyu’s childhood friends you should read it ╮(￣▽￣)╭

The events are organized a little differently in the anime/movie and the manga. The manga is better or at least is more complete, there’s more information about certain scenes so you understand better why somethings developed the way they did. There’s also things that just don’t show up in the anime/movie. For example, at the end of the movie, in the credits there’s a bunch of photos, they’re not random, they’re about things that happened at the same time that haruki and akihiko’s story was happening as well, but didn’t get to be animated (if I didn’t read the manga I wouldn’t understand the photos, I’d think they’re random).
I saw the anime first and then read the manga xD and only realized a bunch of stuff after reading the manga. But the main events and actions are portrayed in the anime/movie.

Pick your poison. I recommend reading the manga and then watching the anime and movie. But they’re all very good, choose you’re favorite way of entertainment and enjoy the ride :)
