So did i understand wrong?
I thought he meant that his memory came back a month after faking he got them (memories) back
No- It took him 3 months to gain his memory back. On the second, month he decided to act like he already got his memories back so he could put hosik at ease since he always see Hosik feeling uneasy and anxious
He never pretended that he couldn't remember. Sunbae would hate to make hosik uneasy
Ohhhh, now I kinda get it. Thank you!
So he was able to gain back his memories after the first month and decided to continue acting like he hasn't. Basically, the succeeding month was just him wanting to hog Hosik all to himself HAHAHAHAHAHAHA
