My boyfriend sent me a text message before Tanabata.

Maybe he wants to know how you're doing now, but he's afraid to disturb your life for fear that you hate him, so he will greet you with a number you don't know, perhaps to test whether you have a new boyfriend ... Second, he wants to bless you silently, hope you are well, and don't want you to know that it's from him, but he wants to protect you silently.
