Senior @ having fun with friends

To be honest, in many cases I can\'t tell which one is the \"senior\" lol. 1st photo: Probably in the middle. Not only do I play double bass, I also play bass. I mean, it\'s the PC club, right? The boys on the left and right are clearly Guinness. It\'s delicious, I can\'t help it. 2nd photo: They all look like ``senpai\'\'. The middle one looks like a 2nd year middle school student, and the left and right sides look like a 3rd year middle school student. 3rd photo: This one is probably right in the middle. The way of stretching like the one on the left is from high school onwards. 4th photo: Which one is it? lol. In terms of atmosphere, I guess it\'s the Pocket guy on the left 2? 5th photo: The hands and arms look unnatural, but they look like they\'re having fun. Probably one of the two in the middle lol. It\'s great that the girl on the left is my friend. 6th photo: Senior: ``I brought you a drink.\'\' Are you really a junior high school student?
