My boyfriend has a fever, but I'm not with him. I want to send him a message to care about him. How should I send it?

Just send a text message to ask him if his fever has gone down, if he has taken any medicine, if he has eaten on time, let him sleep, cover himself up, get dressed when he goes out, pay more attention to rest and drink more boiled water.

Romantic feelings are often reflected in unromantic things. Just be sincere. Your concern for him will move him.
