The 36-year-old TV host-actor showed a photo of him kissing Jessy on the forehead while they are cozily lounging in a pool.
Jessy looked as if she's peacefully sleeping in Luis's arms with her eyes closed and her head comfortably laid on his chest.
Addressing his girlfriend, Luis’s caption read: “Hi wuv ko [heart emoji] relaxed?"
Luis's term of endearment for Jessy "wuv ko" is a sweet baby-talk version of "love ko."
The 24-year-old Jessy also posted a photo with Luis on her Instagram.
It was taken during their trip to Batangas, where they went scuba diving with some non-showbiz friends.
The couple's Instagram followers noted that Luis has become a more expressive boyfriend with the kind of relationship that he has now with Jessy.
Netizens even teased the couple to tie the knot soon.
It was around this time last year when Luis, according to Jessy, started courting her.
Then on December 11, 2016, they confirmed on national television that they are officially in a relationship.
