Male colleagues send text messages

There may be many reasons for texting you at this time.

It may be a simple Valentine's Day greeting (less likely); Maybe he is lonely and bored to send text messages to people he doesn't know very well at ordinary times; Maybe he has a crush on you. Let's test you first.

But in the end, two things may happen. First, his purpose is simple, like you.

Second, the purpose is not that simple, just because there are no women around and lonely.

What kind of situation depends on his personality ~ ~

The above is purely a personal opinion ~ I also suggest that you reply to the text message to explore his purpose ~
