Sekai de Ichiban Kimi ga Suki

Douki-chan is an office lady who is working with Douki-kun in an office. Unbeknownst to Douki-kun, Douki-chan secretly has feelings for him. As Douki-chan struggles to confess her feelings, her rivals, both the kouhai and senpai, continue to vie for his affection.

Futuba Igarashi's new job would be great if her senpai, Harumi Takeda, wasn't so incredibly annoying! Futuba hates his laugh, she hates how big he is, and she really hates that he treats her like a little kid. Just because Futuba is short and looks young doesn't make her a kid, and just because she spends so much time with Takeda doesn't mean she sees him as anything but an annoying senpai...or does she?!

When Kanako accidentally applies to work at an assassination agency, the timid office worker discovers that she has a knack for bumping people off. Will she ever earn the respect of Sakurai, her prickly and kinda hot co-worker–and why is she still having silly workplace problems when she’s employed with hitmen?!

Rilakkuma, Korilakkuma, Kiiroitori, and Kaoru are off on an adventure to the theme park, but with closing time imminent it leads to a series of fun mishaps and incidents as the group squeeze a day of fun into tiny amount of time.

Hotaru works for a famous interior design company. It's a glamorous job, but Hotaru's private life is totally the opposite of glamorous. She lives alone, and when she isn't working, she's mostly lazing about her rented house in training wear. She's really not interested in doing anything, much less dating. "I'd rather lay around than fool around," is her motto. One day her landlord's son comes to inspect the rental property, not knowing that someone is living there. He is shocked at the mess, but not as shocked as Hotaru, as he turn's out to be her fastidious boss, Takano.

Kaoru's unexpected new roommate is Rilakkuma, a bear with a zipper on its back that spends each day just lazing around -- but is impossible to hate.
