I think they were doing a bet ab if they repaired the AC on MCs work, he'll meet Jistar irl Jumin_Kumo
yea basically that and how the mc was still adamant about not meeting irl (cause theyre still technically strangers) and jistar being playful/flirty about meeting irl (constantly asking)
we are getting so close to reaching the "present"
at least to the timeline where chap 1 started off
