Is the plot and characters unrealistic? Yep. But who cares, you're watching anime. This show hits on so many good story writing points. From the pacing, to the character interactions, everything has a very romantic yet poetic atmosphere. Yes, there are some loose plot points, and yes there are some overused tropes. But even then all of these elements mix to create such a heart squeezing story.
I really do want to commend the author of this story. Its often hard to find good consistent motifs in anime these days. This story takes a page out of "A Silent Voice" with the theming of the deaf MC and all the imagery and things that can come from that, but also the usage of texting as a vehicle to convey feelings (something similar to what "Tsuki ga Kirei" did).
Many romance shows tend to try and create a very timeless setting and story, that way people of all ages can watch it at any year and still feel the sort of heartthrob the show tries to convey. Yet this show is clearly a modern romance, with many of the plot points being aware of the current modern culture surrounding many aspects of this show.
9/10 would recommend.
