MKON-044 She saw my message but didn't reply during the art club's training camp

My girlfriend Suzuki is going to an art club retreat starting today. I'm quite worried that she might get into something weird with some bad male club members, but Suzuki says, 'The art club only has girls, so it's fine.' Well, if that's the case, then it should be okay, but apparently another school is also using the same retreat facility. Does that mean there are also soccer clubs from bottom-tier schools? Isn't that dangerous? Shouldn't I worry? The anxious me sent a Line message to Suzuki, but it's been three hours and she still hasn't read it. I'm about to go crazy...
