Deerling transmigrated into the beast world novel she’d been reading before bed, becoming a cannon-fodder deer-beast supporting character. In the current plot, Deerling has just accepted ‘mating’ request of Serpens, planning to use him as her fiancé to survive the winter. However, after transmigrating, she can’t bear to let Serpens experience betrayal and abandonment again. Despite knowing that his departure might ruin her winter survival plan, Deerling decides to ‘break off the engagement,’ but each attempt is interrupted. (Source: Webnovel)
