Is it Jiwan's ex gf? What chap is that when his ex gf was introduced? Huhuhu. I can feel Jiwan's unease expression

No, itβs just some rando who happen to see a mildly popular person and wanted to be friends with them. Heβs looks uneasy because heβs on a date while taken. Imagine having to go in a date and you already have a lover. Even though they said itβs fine, you still would feel awkward, especially if your gay and your on a date with a women.
Thank you Matsuo
