Iyarashii Mannequin: Gachimuchi Suit Seiyoku Zukan

Arata, a salesperson at a luxury suit boutique, views the hottie Makoto, who works in the same shopping mall, as his enemy. Arata is not content unless he's the best at everything, so he gets annoyed every time he seems Makoto...until one day, when he wakes up to sticky bedsheets after a saucy dream starring his rival. Out of shock, Arata ends up finding himself more attracted to Makoto. One night after the mall closes, he sees the lights on at Makoto's shop and decides to drop by. However, when he walks in, he's startled to see Makoto doing the same things he was doing in Arata's dream!!
