Talk:Dosukoi! Kenkyo ni Daitan / Ramen Daisuki Koizumi-san no Uta / Nen ni wa Nen (Nen'iri Ver.)/@comment-131168-20150822200249/@comment-4074115-20150823003230

I guess it's considered one word. Like uses of Ren'ai, the apostrophe is so that it's not misread/mispronounced (nen-i-ri rather than ne-ni-ri).
