In his latest Instagram post, Cruz posted a photo of the two of them, with Adarna kissing him on the cheek.
In the caption, Cruz wrote: "This girl really did something good to my soul. I'll always be grateful."
The two are widely rumored to be dating following a series of posts on Adarna's account.
Last Wednesday, Adarna posted another sweet photo of her cuddling with his "Home Sweetie Home" co-star, apparently taken during their recent Cebu getaway.
It came a day after she called Cruz "baby love" in another post, and after shrugging off critics of their close relationship by sharing that they bonded over art therapy.
Cruz and Adarna have been the center of relationship rumors for weeks now. It began after their much-talked Bantayan island trip.
Adarna has previously gone on the record to say that both of them are not yet ready to enter into a new romance.
Cruz's last relationship was with Angelica Panganiban, which ended in 2016. Adarna, on the other hand, broke up with her boyfriend, Sebastian "Baste" Duterte, back in December.
