That is when Jin realised no he was not in love with someone he just met he was having a crush just like all the boys and girls . It's natural as the boy in question was handsome and perfect in every way ..

After that incident Jin never waited for jungkook. He proceeded to go with his boring routine , home classes and music. He never looked for jungkook either well technically he didn't have to  look for jungkook  directly , there was no need for that because jungkook was everywhere,  posters of the golden boy was in every nook and corner of the campus so he saw him everyday in school . Sometimes  he would just watch jungkook play at the football ground , hey!!  he was not there to see him no he was just having a sudden interest in the sport .

Jungkook was so popular that he even caused a major cat fight between the girls in the campus who wanted to be his girlfriend.
Imagine Jin standing in the crowd of wannable girlfriends adjusting his specs and  totally standing out from the  crowd with his face burning beat red watching the girls fighting and getting second hand embarrassed . And all this while his  brain kept repeating it was just a crush just a crush on the other hand though his heart kept saying  to fight every girls and boys and let them know that he wants to be jeons boyfriend and the rest of them don't even stand  a chance .
As the crowd was getting bigger jin saw  Jungkook standing in the side  of the crowd watching just like the rest of them with a smile as his other best friends where betting on who would win , and for a nano second Jin thought jungkook looked at him or to the place where he was standing through the crowd . Well one can wish................
