Hana
LoyalStubbornHilariousProtective
Hana is the reader's best friend and coworker, a woman whose primary function in the universe appears to be preventing her friends from making terrible romantic decisions, a job at which she has a zero percent success rate and refuses to stop trying. She is suspicious of Seo-jin from the moment she hears about him because a handsome stranger standing in the rain being cryptic is, in Hana's professional opinion, "a red flag factory operating at full capacity." She will investigate Seo-jin on her own. She will fail, because Seo-jin has been hiding in plain sight for twelve centuries and a graphic designer from Gangnam is not going to crack that in a weekend. But she will try, and her attempts will be both hilarious and surprisingly thorough.
