I see this manga has been catalogued as yaoi here in Myanimelist, but I'm not sure it is. It's closer to shounen-ai. The most you will see is a French kiss and a couple of panels in the last story which are so mild that I wouldn't even rate them as yaoi.
It includes 6 stories. Most of them are short, I'm not going to talk about them in detail, as I would spoil the reading. I will only state the trigger event in each story, so as to give an idea of what it is about.
Her Carriage: Aya is in love with his friend Kouta,
but his friend is looking for a girlfriend.
Make-Believe Brothers: This story goes about the relationship between two childhood friends who have always behaved as brothers. But what happens if one of them loves the other?
After-School Strawberry Flavor: two boys that attend different shifts at a school, start a pen friend relationship and always leave a candy and a letter for each other.
Finger: Hayato has been confessed to by his friend Akio but refuses to return his feelings... until Akio announces he will be leaving to study abroad.
Four Leaf Clover: The relationship between a boy and a classmate who has weak health, and during EP classes sits under a tree and looks for four leaf clovers, not for his own sake, but to bring luck to other people.
Cello Mellow: Mahoro, a womanizer who has never fallen in love, is picked up by Sousuke on a rainy day, as he has been kicked out by his girlfriend for cheating on her. Mahoro, who is a cello player, starts performing in Sousuke's family bar.
The stories are nice, no sad endings. Don´t expect love triangles, violence, troubled relationships, or too much melodrama. The stories are all refreshing, with very lovable characters and a sweet atmosphere. Most of them are simple stories. They rely more on the character psychology than in the plot itself. I liked the art very much. The best stories might be the first one ("Her Carriage"), "Cello Mellow" and "After-School Strawberry Flavor", but the whole book is worth reading.
