Why Sean comes off as ingenuine

I think Sean went into the Love Island experience expecting that he was going to jump around, be the villa funny guy, etc (kind of like what Lorenzo has been doing).

I do believe that he really likes Lola, but I think that he wishes he could be having the experience that Lorenzo is having/he wishes he explored more but he isn't enough of a dickhead to go and do that, which is why he is giving weird vibes.

I also think he hates the fact that he is getting like no screen time. I think he just kind of wishes deep down that he had a different experience, but he is still happy w Lola
