1)i remember only side characters.top was a transfer student from italy(?),and he had mid long hair,and bottom was his teacher,who also had glasses

2)in second manga i just remember few details.so the bottom was living in a apartment,he shared it with another guy who was trying to flirt with the bottom.i dont remember the bottoms love story,but his neighbour fell in love with a guy,who fell first,when he saw the neighbour dancing or singing in a club??

The 2nd story can be any BL manga out there, but the first one's interesting, tell me when you find it. ^^
