Trailing Her.
Miss Amaya and the male teacher weren't walking in silence, they were conversing while walking. Ryan could see smiles appear on their faces from time to time as they were conversing.
And you know what? He started getting jealous at some point, he didn't even know the reason why he was getting jealous.
Ryan didn't like that the man was walking alongside Miss Amaya. Put aside the jealousy, there was another reason for this. And the reason for it was that the man could ruin his plan.
Who knows? The man might end up noticing that Ryan was trailing them. And another thing was that Ryan didn't know how long the man would keep walking alongside Miss Amaya.
Would it get to a time when the both of them would part ways? Or are their houses close to each other? So they'd keep walking alongside each other for a long time?
Ryan didn't know...but if the case happens to be the latter, then there was a bit of problem.
