Eigyou no Makita desu

From MangaHelpers:

When Makita stopped for a minute and took a look at his life, he was already 28. Graduating from a great college and working hard in the sales department at Elvis Beer, a highly respected company, has brought him success but his life feels empty. Makita realizes he has been missing romance and, without it, he wasn’t truly living life. He actively starts looking at women from a new perspective but he doesn’t know what he really wants in a girlfriend. [vyc]
