Are you looking to read it officially? I don't think there's an English version for that yet. If you can read Japanese and would like to support the author, read on cmoa. They have a light novel section there. Try your luck with the english ver title if you wanna look around. "I don't want to like you."

Anata Wo Suki Ni Naritakunai (Shinsho Kan De Iapurasu Bunko) [Light Novel] Is the full name, the cover is two climbers together. I can’t find anywhere to read it and it looks really good.
