Upon realizing this, Wataru started keeping an appropriate distance from her, much to Aika's surprise. Did his intentions slip by her because she was getting impatient after arriving at the wrong conclusion? This is the start of a romcom revolving around two people who just can't get their feelings across and both think their love is unrequited.
