Anime 53379 Uchi No Kaisha No Chiisai Senpai No Hanashi Userrecs

Both are romances involving office co-workers, another similarity is that the main female character is a tiny & cute waifu. 

Both take place in an office, with a tiny coworker which is cute. But Katase (Uchi no Kaisha no Chiisai Senpai no Hanashi?) seems more similar to Sakurai (Senpai ga Uzai Kouhai no Hanashi) in terms of personality and "attributes" ;) The show is really chill, kind and cute. 

Both share similarities like the characters working in a office environment and developing relationships between one another. 

a comedy with a small coworker although the story is a bit similar both have a twist to the premise that keep adding more to the comedy related to small girls in office. both are fun to watch.
