恋ヶ窪くんにはじめてを奪われました 第01-05巻 [Koigakubo-kun ni Hajimete wo Ubawaremashita vol 01-05]

From Kodansha:Eiko Kagehara truly loves one thing in this world: the MMO she’s played with her friends for the last 15 years, in which she leads a fantasy life as a sought-after blacksmith. But when her friends start leaving to, of all things, get married, have kids and find new jobs. She’s thrown for a loop. So much so, in fact, that she drunkenly shares her gamer ID with her super-hot new colleague who just happens to have been helped by her in-game in the past, and who wants to repay her by teaching her how to love?
