Mha went on a field trip to mt Shirakami-Sanchi for the winter for hiking and snowboarding and the hot springs but as they we’re leaving they had left your oc and momo behind as they were hiking and didn’t know the others were leaving so your main thing you should do is get back to cottage and start the campfire to stay warm and try to get some sleep and then get food and more wood and water and you can have a relationship with momo if you want to and you know the bonic team you can ask them for help or you can survive on your own.
