Originally released on his livedoor blog, from between February 6th to March 10th, 2008, before being fully corrected and finished by March 18th, 3LDKM is a largely 4koma-based webcomic created by bkub. The series follows a man named Tsuneda who moves into an apartment that comes with a robot maid named Fumimi.
It was entered into the 8th Dengeki Comic Grand Prix in the Shounen Division, where it ended up winning the Excellence Prize. This would later lead to his serialized debut later that year, with Super Elegant in October. Following its first run, bkub would properly cap off 3LDKM's first season on October 11th, with him posting about his new series on G's Festival! later on the 27th.
Later on, as bkub transitioned from his livedoor blog to Twitter and his rc2 page, 3LDKM would have a second season, running from August 10th, 2009, and later a third season, coinciding with bkub getting a new handle on Twitter on October 18th, 2012, would run from October 20th to October 25th, 2012, released on Twitter via Twitpic and on Pixiv.
