Unlike previous arcs, this arc predominantly takes place in the past when John first transferred.
It began on 16th February 2017 and ended on 9th March 2017.
The Project Partners Arc takes place during Seraphina's flashbacks. It details the tumultuous beginning of her relationship with John and reveals how it eventually grew into a beautiful friendship they have today.
After finishing the extra work given by her mother, Seraphina reminisces about an incident from a year ago, when she and John were forced to work on a Literature project together. Needless to say, they were less than thrilled.
Even after a week of preparation for the next portion of the project, Seraphina still doesn't get the perfect score. Later, in the hall, she sees John being beaten up by the other students for defending her.
