Rudy dashed after Reina with various thoughts in his mind.
What would he do by chasing Reina?
The damage was already done, and neither Rudy nor Reina was at fault here. Or maybe Rudy was at fault here.
If he had stopped Reina when he had time, Reina wouldn't have said all those embarrassing things to herself and hadn't daydreamed about kissing Rudy.
It was normal for Reina to act like that since anyone would be embarrassed if the same had happened to them.
Furthermore, Rudy also saw her kissing his phone, the photo which was taken allegedly without his permission.
More than one of Reina's embarrassing moments was seen by Rudy. And what was more awkward was that Reina was seen doing that to her crush, in front of her crush.
There was nothing more embarrassing than that.
Meanwhile, Rudy actually felt good after hearing and seeing Reina. He was happy that Reina thought all that about him.
