Adult couple that boldly being affectionate to each other.

Need some drama recommendation  that similar to:

- It’s okay that’s love

- Intense love

- Jealousy incarnate 

I second Bromance, the chemistry is there all along but when they start falling for each other, man it's so good! 

I tried to give you a sense of the "boldness" of their affection out of 3 stars (***)
