I know there are already some favourite contestants and couples but i want to talk about the unpopular opinion here. The opinions that are not very popular but deserve to be heard and said. 

My first unpopular opinion is that Sian should end with jeongsu.  And Theo should be with someone who reciprocate the same energy.

My 2nd unpopular opinion is that Yuk is a player. I didn’t like the way he ignored youjin. he could’ve tried to talk to her but instead waited for her to talk to him and pinned the blame to her. They could’ve made a good couple. Its sad they didn’t last.

I think if anything, Sian should end up with Yuk. Jeongsu is a red flag, anyone can see that. Including Sian, I'm pretty sure. And like you said, Sian isn't reciprocating Theo's energy (which sucks because I shipped them at the start).

I don't exactly love Yuk, but Sian is the only girl he genuinely made an effort to approach. Like, he was actively playing with her in the pool, and then he made his feelings for her clear. He hasn't done that with anyone else.  He was really vague with Minseol, but he made his feelings clear with Sian. 

From today I would say both Sian and yuk are red flags.

Both Junseo and Si An are huge red flags. For Junseo it’s an ego thing bc he wants to be better than all the guys and get the girl that everyone wants (Si an) Jeong Su is also a player in his own way as he’s leading on Hye Jin, Hae Lin while having Si An as his top pick, so it will be funny to see him crushed / his ego get bruised after he is rejected  by Si An. 

I literally don’t like most of the cast anymore. Theo definitely deserves better than Si An. She takes him for granted thinking he’ll be there for her even though she goes out playing  around and seeking attention from all the men.  Atm I’m just watching for Theo, You Jin, Ji Yeon and Hae Lin. I want to see what happens to them with all this mess lol

I know some people have been shipping Youjin and Theo, but honestly, I doubt they are together. Their chemistry is very friendly vibes, but Theo just recently got rejected. I doubt he will just up and start liking Youjin. The only possibility for them "getting together" is if they plan to choose each other just to get out of inferno.  But other than that, I heavily doubt they have any romantic feelings for each other.

Damn jeongsu won my heart today. 

I am glad  jeongsu choose youjin and didn’t escalate the confusion of haelin hyejin. It was a smart move. And he kept complementing her and joking with her.  It was nice to see jeongsu’s fun side and we got to see youjin more. 

Sian and Junseo's second date wasn't as great as their first, but I don't think it was completely bad either. At night when they had that talk with each other, I think that actually made their relationship much closer. Also, the fact that she is still leaning towards him compared to Theo most definitely means that she is willing to accept those sides of Junseo, or at least just change him little by little. Relationships are like that, you have happy times and then you have debatable times, but if you still choose each other in the end, then all was worth it I guess. I think that the second date was actually good for them cause they finalized their feelings for each other. At least for Junseo. The editing makes it look like Sian is still wavering but she will most likely choose him in the end. 

I do agree that the show doesn't show enough of the other contestants. Like what is Jiyeon going to do with Tehwan? WHat is Youjin going to do now that she basically don't have any time left to get to know Dong ho? Will Dong ho actually get swayed? (I doubt it honestly) And why aren't there more scenes of Hyejin and Janghoon? This dude came to inferno at such a terrible time. I honestly completely forgot that he even existed for a moment and the editing crew don't even try to show that he exists.

HOW IS NO ONE TALKING ABOUT THE CHEMISTRY BETWEEN YOUJIN AND JEONGSU!!!! Like EXCUSE ME !!!! they nailed it together especially in front of the red flag couple. I wish they had something going on. They match each other’s vibe. Also I want to see more and more of MinSeol onscreen. She is soo adorable and funny.she deserves more screen time. I wish they had sent another guy(that 1st one) bcz they seemed to have good chemistry.  Never thought she would become my favourite female contestant!!
