Naru had followed them out of the office and followed them in his car. He recognized the roads. They were all heading to Lin's place. Just when he was stuck behind changing traffic lights, Lin's car sped up ahead. Shit, was I noticed? He jumped as soon as the lights turned amber and raced towards Lin's house. He parked down the street to Lin's place, got out and ran to see Lin carrying Mai inside. From his distance it looked like Mai had simply fallen asleep in the car. The anger in him moved closer to the surface. Lin was touching Mai, was holding her in a way only he, Naru, can hold her.
Time moved on and Lin emerged with Ayako and the two of them left in the car. Naru saw the opportunity and when through the security and up to Lin's place. He patted his pockets for house keys only to remember they had been on his desk at work. He hit his fists against the door. Mai will hear and she'll open it and see me, she always does. The next door neighbour's door started to click and the lock could be heard being unhooked. Naru knew he couldn't be caught now and ran to the fire escape stairs.
He waited there thinking, what am I doing? If Mai used him to get to Lin did she even love him to begin with? Was giving her first kiss to him just a tool? His back hit the wall. His face fell into his hands. He needed to leave and think.
He stalked off back to his car absent mindedly.
What if I really have to let her go?
