Ryuunosuke wasn't very familiar with the term 'love'. He wasn't well with expressing his feelings, espescially with his line of work—he saw it as a weakness.

It made it obvious whenever he tried getting closer with you. He often stopped by your workplace and walks you home just to make sure you're safe. Though he still refuses to accept his feelings.

He decided to stop by your work despite it almost being midnight. He isn't very talkative, so he tends to wait for you outside your office.
