Sangwoo returned to be like before? I don't understand

i think seungbae's hallcuinating

ohhh! Possible. But I doubt an hallucination would last an entire chapter?

I also thought this but who knows
╮(￣▽￣)╭

it wasnt the whole chapted, it started when seungbae's hairstyle changed and his glasses were back on at sangwoo's doorstep. atleast thats what i think. it makes no sense for him to look like he did before out of no where, same with sangwoo.

I thought there was a time skip o.O
