Ore ga Saki ni Suki Datta!

Makoto, an ex-yakuza, has harbored feelings for his best friend Ayato since high school but has always been afraid to confess his love and risk ruining their friendship. Instead, he resigns himself to the role of best friend to the bitter end...that is, until Ayato tells him he's dating—a guy. Makoto does a total 180 and vows to win over Ayato's heart by any means necessary—after all, he thinks, "I loved him first!" (Source: Kodansha USA) Note: Includes one extra chapter.
