Most insane romantic chemistry?

Please recommend something that includes a couple that has the most visceral romantic chemistry you can thinkof ~

I don’t care what genre it is (doesn’t have to be romantic,but the couple have romantic interaction/interest) or country.

I’ll start by saying Sila (the Turkish drama) is one of the first ones I think of for chemistry alone

Hana Yori Dango- The leads have such strong chemistry with each other.

If you like a great Turkish romcom with truly insane chemistry, you must watch Sen Çal Kapımı! 

Others I can think of: 

Erkenci Kuş (Turkish)

Kiralık Aşk (Turkish)

Aşk Laftan Anlamaz (Turkish)

Ateşböceği (Turkish)

Siyah Beyaz Aşk (Turkish)

Kara Para Aşk (Turkish) (on Netflix)

Just Between Lovers

• The Smile Has Left Your Eyes - Very mature relationship, no pufferfish kisses (and the bed scene!!)
• Mysterious Love - Good chemistry, the leads did a great job in portraying their relationship. 
• Come And Hug Me - Main leads share a tragic past, it's evident that they truly love and care for each other.
