Agree to some comments here in this video that there's no chemistry at allhttps://vm.tiktok.com/ZS98LTMyYK4CY-Z1MrB/
In fact, the chemistry at the beginning is natural in general, especially since it's only 4 eps, they've just met, the story is 40 eps and you judge it's just the beginning, the romance is normal in the middle until the end... so far it's still good and enjoyable...
