This is mainly a review episode. At the beginning Sumomo warns Shinbo that she is running out of room in her hard drive and needs to delete some files. She runs a check and the first file is the dance she did when Shinbo met Hideki. It shows a flashback to that and to when Hideki found Chii. Then when Sumomo crashed and Hideki went to visit Minoru. Then Shinbo comments on how loud things have gotten since Hideki arrived. We see flashbacks of Hideki meeting Hibiya and making a fool of himself in front of her, then when he met Shimizu and Hideki making a fool of himself in front of her also. Then we see when Hideki was looking for a job and met Yumi. A scene when Hideki was being perverted in front her. The second file in Sumomo’s hard drive is the info from when they went to the underwear store. We see flashbacks from that event. The next thing on Sumomo’s hard drive is the incident with the peep show and when they had to recharge Chii. There are flashbacks of when Hideki was trying to recharge Chii. Sumomo comments on how Hideki really cares about Chii and we see the flashbacks from the peeps show incident. It then starts showing a bunch of random clips of Hideki while Shinbo evaluates Hideki’s personality (he’s loud, talks to himself, stupid, and it’s tiring to be around him). Sumomo is waiting to delete the files but Shinbo says to keep them and he’ll give her more memory tomorrow because Shinbo has to return it to Hideki someday.
