It follows Anton Danyluk making a move on Anna ahead of the first recoupling of the series.
In this evening's show, Sherif takes Anna aside and confides: “I wanted to fill you in on a discussion that me and Anton had. That was me basically telling him how I feel about you.
"I do want to persevere with you and I really like you.”
Anna jokes: “That’s funny. You told him you like me before you told me!”
The pair laugh and Sherif continues: “I’m telling you this now. I just thought I should tell you that I’ve told him I really like you and I want to try…not that I’m getting protective.”
Anna asks “Do you get jealous?”
Sherif admits: “I do get jealous. I’m not going to lie. I like you.”
Anna reflects on their chat in the Beach Hut and says “I like that he likes me because maybe we can put in more effort and see if it goes anywhere.
"But at the same time, I don’t want him to because I’m scared that if it doesn’t go anywhere, he might be upset.”
Will Sherif put in the graft and win back Anna?
Love Island 2019 airs tonight at 9PM on ITV2.
