ML is a stalker

I like the story premise. I like Cong Rong. She is a great lead actor. Determined, smart, a good friend. I would like the ML except to me he is a creepy stalker. I know for dramatic tension he is not revealing their history. But to me he is still a stalker. I will keep watching because of Cong Rong and wonderful supporting characters and their stories. I am not fond of stalkers. The site reports review must be 500 characters in length which is pretty restrictive. And still not at 500 characters so and additional unnecessary line.
