• Portal — yes 4= "Do Your Best, Douki-chan" is a collection of illustrations by Japanese artist Yom. The doujinshi manga was serialized online via Yomu's Twitter account from September 2019 to May 2023. Eleven volumes were released from May 2020 to December 2023. A short-form 12-episode original net animation (ONA) adaptation by Atelier Pontdarc was released from September to December 2021.

The story follows Douki-chan, an office lady who works with Douki-kun. Unbeknownst to Douki-kun, Douki-chan secretly has feelings for him. As Douki-chan struggles to confess her feelings, her colleagues, both the kouhai co-worker, and their senpai from a related company, also vie for Douki-kun's affection.

• Douki-chan • Nene Hieda • An office worker at a Tokyo-based company. She is a serious worker and promising prospect within the company. However, she is inexperienced when it comes to romance, and is unsure of how to approach the man she has feelings for. • Douki-kun • Junya Enoki • The male office coworker of Douki-chan and Kouhai-chan, who is drawn without visible eyes. He has a romantic interest towards Douki-chan and often goes to look after her when she gets isolated, but is too shy to confess his feelings to her. • Kouhai-chan • Sumire Uesaka • A coy woman with a soft vibe who is always smiling. She is a junior in the same department as Douki-chan and Douki-kun. She is always trying to seduce Douki-kun and isolate him from the other girls. She enjoys cosplay, picking popular characters and leaving Douki-chan with less attractive mascot costumes. Many other men are attracted to her. • Maiko Okuzumi / Senpai-san • Asami Seto • Maiko is a woman with a mature female aura, and is the only character with an actual name and a visible name tag. She is currently an employee of a business partner. She is free-spirited and likes to drink. As Douki-kun's senior in college, she was very close with him, but had turned down his confession, saying that she was already seeing someone. Her younger sister is Yuiko Okuzumi from the author's related web manga Miru Tights. • Shinchin-chan • A girl with short blonde hair who gives Douki-kun a kiss on the lips the first time they bump into each other. She becomes an intern in their department, and later a permanent hire. She easily deduces that Douki-chan has a crush on Douki-kun. In one of the chapters, she tells Douki-kun that she joined the company because she likes him romantically too, but quickly adds "just kidding".
