Not to be mistaken with the Boyfriend (Beta) Anthology manga, this is a collection of very short side comics which were released from April 2016 to October 2017 as in-game rewards in the Japanese mobile/browser game called Boyfriend (Beta) (a.k.a. ボーイフレンド（仮）).
These comics are intended to show the point of view of the 45 in-game characters from their respective in-game scenarios. The whole scenarios can be unlocked by playing the game.
