My favorite weather is cloudy, and Mandarin lasts for three minutes.

Then why do you like cloudy days? What sensory experiences have cloudy days brought to you, what emotional triggers have been induced by these experiences, and what events have caused you to particularly like cloudy days. These can be said, especially the details, so you can say a lot of things. Even if you haven't finished it, you won't be deducted when the time is up, because it's not that you haven't finished it, but that time is not enough.
