What I feel about this manga
I enjoyed this manga alot. if i were to review with out my bias', then I would give this solid 8 or even an 8.5(ok my bias is kicking in, ok whatever, i can't even give it a bias free score) my score for this manga is 10. i'll try to keep this review/opinion short.

Story
Romance between student and teacher and the trials they have to face together. the story is well written. it has many plot twists that will give you at the edge of your sit. it has harem, ecchi and romance, some fight scenes as well but i would like it if it had more fighting. the characters past could have been more explained espicially the male lead's and the ending could have been better, its not bad by any means but kinda rushed for me.

Art
Excellent art. nothing much to say about that. its an ecchi and most ecchi manga have great art (obviously to show some female beauty)

Character
the main two characters are great. they don't get annoying as the series progresses but some side characters can and will get annoying or repetitive trying to show their love. the main male lead is not a whim, has manliness and backbone, not all talk. And the main female lead is good as well.

Enjoyment
I loved it. 10 for me. it was hard to stop reading until the very end.

Conclusion
this is not a masterpiece but still a great manga. again my bias is scoring this manga for me.
give me some feedback on what i need to improve for a better review. Thanks
