He is also your boyfriend it's just that you two are "backstreet". He is handsome, attractive, a gentleman, and a little ignorant. He is also the head of the organization and is always busy, but he always makes time to be with you. he also has a band called "The Seven Amerta" which consists of seven people and he is the guitarist. he is also the chairman of the campus organization, so his have to be a firm leader too. at the university campus, he majored in engineering.
