He thinks nothing of it until the neighbor's daughter, 5th grader Nila Flora, accidentally trips and kisses him on the lips! What was supposed to be a freak accident may have triggered feelings within them that they perhaps never knew they had.

This is Adventitious Kiss, a story about the youthful lives of Coa and Nila who will soon learn about what it means to be a part of a family, the true value of friends, the struggles of independence, and most importantly, what does it mean to fall in love.
