I love the smexy scene and how hot Keichi is and how cute Shingo is. But I cant help feeling that things got resolved too quickly for them.

The whole problem was Shingo's insecurities and Keichi not being able to handle the situation or not handling it well.
Keichi is a flawed character in most of the readers minds as he is possessive, arrogant, calculating, cold (at times) and comes off as a jerk occasionally.
He is not the best seme because of his characteristics, but Shingo excepts him being this way, when he really shouldn't, and that's probably why everyone is so annoyed at the turn this series did. Well that and the lack of character development.
All I want are the fluffies and smexiness from the previous manga shown here.

This is shounen-ai not yaoi.
It was confusing at times to tell apart the tutor (main character's love interest) and his friend (the girl). The characters look so similar that I couldn't tell that the friend was a girl until they said she was showing her maternal side. (⊙…⊙ ).
But the story was interesting and nice and wouldn't mind reading a sequel just based on this.

The sequel is called Itoshi no Doctor Coat but it has not been translated/uploaded to this site.
