At home, her spiritual mother bestows upon her a new collection of charms, meticulously crafted by the same shaman Sung-ah had previously consulted, after her previous set was lost in battle against the aquatic apparition.
The subsequent day, Sung-ah is singularly focused on placing the charms close to Gyeon-woo for his protection. With Ji-ho's connivance, she resorts to stealing his phone, and while covertly inserting the charm inside its case, they are caught red-handed by Gyeon-woo's grandmother, who had popped in for a visit.

Yet, Sung-ah stands firm in her resolve to lend him a helping hand, unwavering in her belief that he possesses a good heart.

It transpires that the specter lurking in the storeroom was the one assaulting him. Ji-ho arrives on the scene, fire extinguisher in hand, just in the nick of time to lend a helping hand. However, whispers of suspicion still subtly linger around Gyeon-woo within the school's corridors.

The coach, having engaged in a conversation with Gyeon-woo's former mentor, comprehends the depth of his abandonment by teammates and the weight of unfounded rumors that have plagued him.

However, Gyeon-woo politely declines, voicing his reluctance to let his grandmother witness him being despised once more.

She unfolds the tale of how misfortunes have relentlessly haunted him, to the extent that even his own parents have severed ties with him.
