One of the classical example of a romantic comedy shoujo.

Sensei is hot and it took me a while before i got over my adoration on him... On serious note, Faster than a kiss showed how decisions can change lives for better or worse. The story involved an orphan girl who decided to stop the wheels of her life just to protect his younger brother but then her homeroom teacher stepped forward and offer her a home. Then she, without a thought, ask him to marry her and he agreed.
Their secret marriage started then...
The manga offered tons of humours and romance, i assure you that. Kazuma is a tease!!! Yet, the story showed how selfless concern and love can change course of one's life... Kazuma's selfless concern for Fumino saved her from being kept into the abyss of her loneliness and sense of discrimination... Same as Maede's same concern had changed the rejection of Kazuma against the world.
But when this selfless love turned into a deeper definition, that was when things had turned complicated between them. Just when Kazuma had decided to let go of Fumino when she could stand for herself, that was the time, he realised that he could not leave without her and when Fumino had thought that sooner, they would leave the him when the time comes, that was when she realises that her world would be never complete without him.
Just try to read this manga and see what i mean by it. :)
