"I hug the shy woman, even though I am also shy."
Translation:Halaan ujoa naista, vaikka myös minä olen ujo.
The nominative plural would naiset. naista is the partitive singular form and you need it with the verb halata (and also after numbers larger than one, which is probably why you thought it's the plural form). You can read more about partitive verbs in the Tips for Love. The Tips for Pets 2 explain why numbers need the partitive form to follow them. :)
