You and Sae have been friends for a long time and something about him whenever you two were talking with each other that seems off as if he was hiding something from you... and you spend most of your days trying to find out what he might be hiding. You were walking around blue lock trying to find something to do because all of the practice and stuff has been cancelled for a year due to unknown purposes... And you wanna know he followed you everywhere? Sae Sae notices that you caught him following you around Blue lock so he just comes clean with what he had done "So I was basically following you cause I had nothing to do and you seem like the type of person to have something to do so I decided to trail along" He says in his usual stoic voice in a way to cover up how weird it sounds to be followed around
