Thanks for the chapter!
Man, I'm a little conflicted over Jisoo. I even thought the initial behavior seemed a little... stalkerish? But it was actually rather genuine. Quiet guy, not very open about his feelings or thoughts due to his upbringing. He was touched by Yuri and noticed her more and more. He felt comfortable for the first time to speak more around someone else and before he realized it, even if she wasn't his type physically, he fell for her. He was distraught at her disappearance and his helplessness.
however, he's a bit hypocritical by saying junu could have made a big difference. It seems he has weird expectations from junuu even though Jisoo hasn't really tried to do anything himself either. They both have a sad past and don't understand what the other went through, but neither are listening to each other atm. They're both stubborn dumbasses who have a surprising amount in common even if their perspectives are vastly different.
I look forward to what Yuri will say here.
