(Future Fights First: White Fox#1 (fb) - BTS) - Yeji was very interested in Korean folklore, and she was the president of the folklore club.

    Sul became friends with Ami Han, a new student/classmate at her high school classmate, although she was unaware that Ami was the last of the kumiho, a mystic race of vulpine shape-shifters.

    Yeji enjoyed reading "Tales of the Imuldan: A History of Korean Folklore" so much that she read it twice.

(White Fox Infinity Comic#1 (fb) - BTS) - Yeji's favorite food was beef tongue.

(Future Fights First: White Fox#1 (fb)) - After congratulating Ami on the winning play in a volleyball game, Yeji shared that she was particularly enjoying the chapter about the kumiho. As Ami feigned ignorance, Yeji told her all about the kumiho and that she wasn't sure about legends that described them as evil. Ami said that since they weren't really that it didn't really matter, but Yeji told her that it was fun to imagine and that she sympathized with being judged for something that was not her fault. She further noted that in her opinion, some people deserved to have their hearts eaten.

    They were interrupted by a quartet of mean girls, who mocked Sul as being in the "Loser Book Club," and when Ami stuck up for her, the advised her to stay away from Sul and related her father's problems. The girls further warned Ami that if she stuck with Sul that she would get kidnapped or have her organs stolen, but Ami defiantly told the girls to back off. 

(Future Fights First: White Fox#1 (fb) - BTS) - Yongsan Brothers' agent Junho failed to get money from Sul's wife.

(Future Fights First: White Fox#1 (fb) - BTS) - Reporting to his boss, Yongsan Brothers lieutenant Kyuntae Kim (actually a samjokgu, a mystic three-legged dog that was the enemy of the kumiho) battered or slew Junho as an example to the rest of the crew.

(Future Fights First: White Fox#1 (fb)) - Kyuntae Kim and his agents confronted Yeji and forced her to come with them.

(Future Fights First: White Fox#1 (fb) - BTS) - After Yeji failed to show up for class or answer texts, Ami correctly suspected that something was wrong and went out looking for her. sul-yeji-wfic1

(Future Fights First: White Fox#1 (fb)) - After fighting her way past underlings, Ami, in her White Fox form, found Kyuntae Kim sitting by the blindfolded and bound Yeji, who recognized her voice. As Ami fought Kim, Yeji shouted for Ami to eat his heart. After Ami wounded him (costing him his left eye) and approaching police sirens were heard, Kim fled, while Ami untied Yeji.

    After Yeji asked her if she had eaten his heart, Ami told her organ meat was too rich for her, and Yeji told her not to be boring, asking if she had hot pot. As they exited the building, Yeji was impressed by the number of police cars, which Director Jung of the South Korean National Intelligence Service recruited Ami to work for them.

(White Fox Infinity Comic#1 (fb) - BTS / White Fox Infinity Comic#2 (fb) - BTS) - Yeji became a professor of folklore at Seoul National University.

(White Fox Infinity Comic#1 (fb) - BTS) - Yeji usually invited Ami to dinner when she had something big she wanted to tell her about.

(White Fox Infinity Comic#1 (fb) - BTS) - Yeji found Seoul's hidden supernatural community -- including dokkaebi, cheonma, multiple kinds of gwisin, as well as a jeoseung saja (death god), whom she considered to be really hot -- and learned that someone was killing them.

    Yeji invited Ami dinner and arranged for the supernatural community to meet them there.

(White Fox Infinity Comic#1) - Yeji met Ami for dinner. Reminded of how much Ami ate, she asked if that was "a kumiho thing or a you thing?" After Ami asked her if she had a new book of folklore coming out, Yeji told her about someone killing members of Seoul's hidden supernatural community. After Ami told Yeji that she would like to meet these supernatural, Yeji had them come out to meet her.

    As the beings proceeded to tell Ami about how their members and relatives had been torn apart by something wolf-like, the discussion was interrupted by the death god noting that death was approaching. She rushed to find another dead dokkaebi, and she recognized the wounds to have been from a samjokgu.

(White Fox Infinity Comic#2) - Yeji was present as Ami told Tiger Division about the killings, which she felt pointed back to the Yongsan Brothers. Ami introduced Yeji and related how she was both a witness and an expert on the matter of folklore/supernatural, as well as experienced with the Yongsan Brothers. Yeji detailed hos samjokgu were predators whose whole purpose was to hunt and kill kumiho.

(White Fox Infinity Comic#2 (fb) - BTS) - As White Fox met and subdued Kyuntae Kim, an immyeonjo was killed downtown.

(White Fox Infinity Comic#2) - Yeji related this to Ami, and they both realized that the real killer was someone else.

(White Fox Infinity Comic#3 - BTS) - After revealing that two of his samjokgu had been slain by this same killer, Kyuntae Kim convinced Ami to work with him to stop the killer. As Kim traced the killer's energies, she  -- noting herself to be of the Sunset Order -- used paper talismans to sap Kim and Ami's strength and then offered to gift them merciful execution.

(White Fox Infinity Comic#4 - BTS) - The Sunset Order member noted her goal of purging foul demons and spirits from the world, which she had done with paper talismans in the form of samjokgu. Via a piece of Swordmaster (Lin Lei)'s' Sword of Fu Xi, White Fox destroyed the paper talismans, restoring her and Kim's powers. However, following defeat, the Sunset Order member claimed to be nothing and left behind only her paper form.
