I sent a WeChat, but he didn't reply, and he didn't reply to the message. Does he love me? He is off work now, so he can't be so busy. He is an interior designer.

If you send a boy a WeChat, but he just doesn't reply to you, even if you send it to him, it doesn't mean he doesn't love you. You said yourself that he is an interior designer, so he must be very busy after work, so he probably just didn't notice his mobile phone. Even after seeing the text message sent to him on your mobile phone, he may just want to get off work quickly and finish today's work tasks. After all, he is an interior designer and can't finish his work during the day. He had to work overtime to finish the work. So you have to be considerate of him.
