During episode 5 of "Paradise Island", Mạnh Kiên – Cheon Minuk – Khánh Linh brought unexpected developments in their private date.
The date began with Mạnh Kiên and Khánh Linh dancing together by the beach. This left Minuk feeling like an extra person.
Minuk said: “I didn't want to see that, I truly didn't want it at all. Because I thought I couldn't lose, so I asked Kiên to teach me how to dance, but he taught me in a very reluctant manner. So I also learned in a very reluctant manner. I didn't want to lose”.
As for Mạnh Kiên, he said: “Actually, I wanted to get to know all the female contestants, not wanting to love all of them”.

However, an unexpected development occurred at the dinner table when Mạnh Kiên said he was worried about Yuna Vũ.
“He ate instant noodles at home too, but he wanted to talk to her. All the girls had gone on dates, but she hadn't. So, at the moment, he wanted to talk to Yuna Vũ again, talk to her like two friends. So, let's stay and enjoy it, okay?” Mạnh Kiên said and left.
Witnessing Mạnh Kiên's actions, Minuk and Bùi Khánh Linh were both stunned. This also caused frustration for the advisory board.
Diệu Nhi commented: “Mạnh Kiên said he was worried about Yuna Vũ's emotions at home, but what about Khánh Linh, he was dating Khánh Linh”.
Á hậu Thảo Nhi Lê expressed her opinion: “I think he didn't respect Linh, went out with Linh and then left her alone”.
Khánh Linh shared her feelings after the date: “I felt like I wasn't respected, chose to go on a date with me but didn't finish the date and then went back home with a strange reason. I'm not unhappy because he didn't like me, but I'm unhappy because he didn't respect our conversation”.
After returning to the shared house, Mạnh Kiên searched for Yuna Vũ, which surprised her. When Yuna Vũ asked Mạnh Kiên about his date with Bùi Khánh Linh, Mạnh Kiên replied straightforwardly: “I didn't enjoy it as much as the date with you!”.
“Honestly, I had already gotten into the car with you, but I chose not to because I wanted to get to know Linh better. I chose someone else and then came back here with you, I saw you like that and I was very happy”, Mạnh Kiên said to Yuna Vũ.
Episode 5 of "Paradise Island" ended, leaving the commentators regretful about the unfinished relationships of the couples after the date.
