Fifteen-year-old Nanaka Kinoshita has arrived for her first day of high school, alongside her childhood friend Meiko. While Meiko is a typical girl, Nanaka is in love with painting and finds it's easiest to express herself with art, rather than with words. As she walks onto campus with her sketchbook, she spots a handsome boy with his own sketchbook in hand; his name is Chihaya, and he's one of two members of the school's art club. Nanaka wants to know as much as she can about Chihaya, and together the two girls join the art club. And soon, Nanaka discovers that she and Chihaya have more in common than she realized...
Nishino (Hidarite no Love Letter) and Nanaka (24 Colors) are both quiet and shy girls that have their heart set on a boy they think is out of their league. Though they each manage to push that to the side and pursue their guy in their own cute way.
Sixteen-year-old Miko Ousawa has just moved to Tokyo to fulfill her dream: to work at the famous bakery Saint Molly! She's quickly taken onboard by the bakery's assistant manager - a boy her age - and is pulled headfirst into the challenging and demanding world of artisans. From running the cash register, to helping knead bread, to giving suggestions on how to improve the store, Miko is in love with her new craft. However, soon, Miko finds herself falling for her employer, especially since the two live in the same apartment complex!
Love soon develops between two people of with the same interests. They find themselves realizing how similar they are. They both love their art/craft and both think and in the same way. In both manga, the pair are surrounded with friends. Also in both manga, they have a friend who would help them realize their love.
In 24 Colors and The Sleepy Residents of Birdcage Manor, the main focus is on an artist, The two series both show the life of an artist and there are similar plotlines in both. The protagonist falls in love with the artist. The male artist is an anti-social recluse and acts distant from the protagonist. The male artist's friend is cheerful and outgoing and in love with the protagonist. With a second girl, a love square is formed. The endings are very similar. Personally, I liked Birdcage Manor much more but I enjoyed reading both as the romance wasn't the only plot element. There was insight into how an artist thinks and the beauty of the world. They both have very pretty art as they're both about art!
