Hello

I remember seeing a clip sometime ago, where hero is sitting on the sofa in the heroine's home and she is getting ready to go out somewhere. While heading out, she stops near the door and tells the hero not to wait for her as she will get late, I think because she's going on a date (that's what I remember telling him, to make him feel jealous I think). Its a time travel love story where the hero is a king and he time travels in the present time and stays with the heroine. Its a Chinese drama most probably, but I really can't remember the details as I have seen the clip sometime ago. But its a recent drama 2016-17. 

If someone remembers the drama from the scene I have described above, please help me out. Thank You! :)
