RyanAir Stansted overnight layover, do I have to leave and re-enter?

Hi! I booked two separate flights with RyanAir. The first one from EDI to Stansted which arrives at midnight, and the second one from Stansted to Spain at 9am the next morning. I will camp out in Stansted airport for those 9 hours and was wondering if I have to leave the Gates and re-enter through security or if I can just stay at the Gates once I have arrived, like a normal connecting layover, waiting for my next flight? I won‘t have checked bags, just my hand luggage. I know RyanAir doesn’t technically do connecting flights, but since there is so much time between my two flights and I‘m travelling with hand luggage only, I was wondering if staying at the Gates is possible. I have only ever been to Stansted once and that was a long time ago, so I don’t know the airport too well.

Please don’t tell me to book an airport hotel, I know that’s an option, I just want to save money and know the risks and the horrors of staying in an airport overnight, it won’t be comfortable but it was the cheapest and easiest option for me this time.
