Koe no Katachi gives some of the same vibes as Kaoru Hana wa Rin to Saku. So if you enjoyed Koe no katachi then you will most likely enjoy Kaoru Hana wa Rin to Saku.
As a quick note: The drama in both is also decently similar to one and another, with the whole looks like an asswhole but really isn't.
