Tsugai ni Narenai!

Ritsu is an omega who has just enrolled in the same university as his first love, Satoshi, who he's been pining after since he moved away six years ago. Remembering how Satoshi told him he would love to see Ritsu's "sexy and perverted" side someday, Ritsu is determined to use his sexual prowess to win Satoshi's heart - even if the only knowledge he possesses on the topic was gained from solo sessions between himself and his vibrator. As Ritsu struggles to keep his lack of sexual experience a secret, Satoshi is keeping a secret of his own: He's been hiding his sub-gender ever since Ritsu mistakenly assumed that he was a beta back in middle school. An alpha pretending to be a beta and a "slutty" omega who has secretly been saving his body for the man he loves... just how long will it take these silly boys to realize that love and lies are never a good combination?
