Mousou Telepathy is a perfect example of a manga that evolves as it's written. I feel like the author originally started the series as a gag comedy, but started to become so engrossed in the characters that he/she started to expand the idea into something much greater. Honestly, when I started reading it, I was just trying to kill some time and was in the mood for some ecchi comedy. However, over the course of the manga, the genre gradually morphs from a 4-koma ecchi gag comedy into a romantic drama/comedy about mind-reading. The comedy is still there, but the serious plot aspect becomes much more pronounced. As the genre morphs, so too does the presentation format. Even though it's still technically a 4-koma format, the standalone pages start to blend together until you start to feel like you're reading full-length chapters, though there are still occasional standalone pages.
If you're just looking for some silly ecchi gags, you'll enjoy this manga up until a certain point, but eventually it does change, so if you're not interested in investing yourself in the characters and reading an actual story, you may lose interest there. On the other hand, for those of you who want an interesting supernatural romantic comedy with some depth but have no interest in ecchi, I recommend just putting up with the early ecchi focus. It actually becomes a very relevant and purposeful plot point later on, so it's worth reading through it to get there.
Overall, I've given this manga a 7 on MAL (7.5 on my personal scale). It's more than just your average ecchi gag and turns into what is actually quite a good romantic comedy.
