We had our final lab today 😭😭 which means that this trip is almost over and it was a rainy day too. We did the optics lab today and it was fun to play around with the lens. We had a hard time to find the angle but thankfully we still manage to do it. After that we went to a traditional house near Kookmin University. We just sat down by the side of the house and enjoy the sound of the rain. It was a very zen place to be.
