Empty Heart
Résumé
High school art teacher Jun Usami has loved his best friend Ryuuta Kajiwara since they were students themselves. Unbeknownst to Jun, however, Ryuuta's younger brother Takumi has been in love with Jun ever since he caught "Usa-nii" stealing a kiss from his sleeping brother. Now that Takumi is all grown up and the spitting image of his older brother, he's willing to do what it takes to win Jun, starting with taking Jun's art class. Then, when Ryuuta announces that he is engaged, Takumi takes the opportunity to offer himself to Jun as a substitute for his brother. But Takumi is not some art class plaster model; he's a flesh and blood human with a full heart.
