'Sooner or later… the thief will show up again!'
That was Rey's ideology after realizing his property had been stolen.
For the duration of the three days after this discovery, he gave several windows of opportunity, but the thief did not take the bait.
This meant his opponent wasn't merely a reckless individual, but someone smart enough to recognize how to exercise caution.
Still, Rey wouldn't give up.
By pretending to go to the Library, but then using [Stealth] and [Mimic] to return to his room, he could intercept the thief.
'Looks like it worked…' Rey smiled while looking at the pained expression of Noah.
He had used [False Pain] to disable his target since he had the [Phase] Skill.
'[False Pain] just replicates the feeling of pain, so as long as I don't physically harm him, it's fine.'
Now that Noah has become docile, Rey thought it was the perfect time to stop the Skill.
