Engage manga volume 3 features story and art by Yuu Minaduki.

Mei's bold confession to Naru leads to a moment of intimacy as the two try to identify the emotions now brewing within the older man. But when Mei discovers that Naru's protection has always stemmed from a combination of duty and selflessness, a nagging doubt arises. Is it possible Naru's acceptance of his confession was out of mere obligation and not genuine love?
