Replacement

At school, Y/N and her 7 friends were hanging out inside their classroom before school started. The teacher introduced a newly transferred student to the class, and they got to know her name was Tsuki. Y/N and her 7 friends slowly became friends with her. When Eric heard about her being friends with Tsuki, he began to warn her every day, but Y/N didn't take him seriously. Y/N started spending time with her friends 24/7 and everyone felt safe around each other. One day, Y/N's 7 friends begin to change their attitude toward her, and they slowly stop hanging out with Y/N and leave her out of every hangout they planned. Everyone else continued to hang out with Tsuki and gossip about Y/N. On Y/N's birthday, she invited all her friends to come but no one showed up. Eric on the other hand noticed what was going on and he decided to invest in Tsuki and the 7 friends secretly and silently. Eric and Tsuki knew each other but their relationship didn't end well.
