I miss my cousin, what should I tell her?

If you miss him, you can tell him directly without being embarrassed. What age are we now? We should be more open-minded. If you have anything to say, just say it and don't say it. Don't say it without any regrets. If you don't say it, then you really really like him. You will regret it for the rest of your life if you go. come on! All your wishes come true. Happy every day.
