Secret Reptiles or Himitsu No Reptiles is a great read. The concept can be a bit of an acquired taste but definitely worth the read. Slight fanservice but definitely not like it relies on fanservice. The romance aspect is perfectly implemented as well. Highly recommend. The story is unique and strongly supports its romance genre. The art style is extremely clean and has a subtle cuteness. The characters were extremely well-developed and I think that manga fans from multiple genre preferences will enjoy this. I find that the female protagonist "Nagara Naga" is extremely-lovable and grows in character strongly from start to finish. In fact,the manga is about Nagara Naga's love for reptiles and her growth in finding the beauty in all pets as well as her romantic growth between herself and her soon to be boyfriend.
