It's an old forum, but I want to still talk about this since I recently came across it on Facebook post. The manga ended on a bittersweet note, to no surprise as it's a promotional for the light novel. It's a really good series, so I do hope it gets licensed. Frankly, if the manga is anything to base on, it's that the light novel is filled with fun interactions and witty dialogues, something only few light novels possess. One of the more famous works of the author is Onii-chan Dakedo Ai Sae Areba Kankeinai yo ne! or OniAi, and I would compare the two, I'd say MonRabu is a far better work.
Well, I said my thoughts, and if this, and I pray, ever gets picked up, I would become a member in a heartbeat.
