The Transcendent One-Sided Love of Yoshida the Catch 3

Hibiki Yoshida has perfect good looks, enough smarts to graduate top of his class at one of the highest institutions, and is one of the most promising up-and-comers in a huge international company. He's a total catch and the envy of the whole world. But this apparent superman has just one dream... “To walk down the aisle with the girl he loves”!! Ever since they were students together, Yoshida has been in love with a bafflingly dense woman named Sena Shimakaze. Day after day he carries these tragically pointless feelings in his heart while he helps her with both work and life, round the clock, even going so far as to sacrifice sleep. But one day, Shimakaze and her helpers are roped into being temporary assistants for another mangaka, Tokiwa, an old friend of Shimakaze from school. Are we seeing the sudden development of a love triangle between Tokiwa, Shimakaze, and Yoshida?! What will this mean for Yoshida's own romantic feelings?! Will they be able to get the manuscript finished on time…?
