i'm not crossing the lines

listen, this 2nd semester. We were distributed to our respective company or office, and i happen to meet this person from another school, who happen to be a student-trainee like me...she sits beside me and its a pretty cramped office and we often touch our shoulders and sometimes accidentally have an eye contact. it's been weird lately...i forgot to tell you_ she already has a gf and i don't like the way her gf looks at me, i think she knows...nothing else crazy is happening just everyone around me...they must have sensed something, and they reacted so differently...it's weird because my friends also tease me about this person, i only talked about this person once wtf and i have to changed topic and another topic that's definitely more interesting than that i hope they won't notice. i am attracted to her but its only temporary i swear! And another thing is lately i am attracted to people who are already taken...idk maybe i am i just paranoid
