In this manga, a japanese boy moved into the apartment flat right across from the seme. This is taken place in France I think? All I remember is that the seme always fall in love with the person next door. This time he fell in love with the uke at first sight. Although he didn't know the uke is a boy but after talking to him, he fell in love. The uke's name starts with 'Fu' and the seme and his friends were unable to pronounce it so they call him with the 'U' instead. Please help me find it! Thank you!
