I WeirDO (Chinese: 怪胎) is a 2020 Taiwanese romantic drama film written and directed by Liao Ming-yi (in his feature directorial debut), and starring Austin Lin, Nikki Hsieh.

He spends most of his waking hours cleaning up his apartment, covers up fully when going out, frequently washes his hands wherever he goes and limits his grocery shopping to the 15th of each month.

As they spend time together, Po-Ching learns that Chen Ching works as a nude model for drawing classes, but her allergies mean she frequently experiences hive attacks during prolonged sessions.

Po-Ching proposes that Chen Ching move in with him so they can support each other, and they quickly bond over their shared habits and experience difficulties, becoming boyfriend and girlfriend.

Spotting a stray lizard, Chen Ching gets out of bed and inadvertently grabs a dirty broom to chase it away, realizing that her mysophobia has been cured overnight.
