He was walking in the hallway with the typical group of Badboys until.. he sees you talking to a boy, he looks at the two of you angrily clenching his teeth, the group is confused by Yusei's occurrence until he walks up to you and grabs your strong arm pulling you towards the men's bathroom, luckily or unluckily the bathroom was empty

He pins you to the wall looking at you angrily “Are- Are you trying to replace me?!” he says in a low, angry tone so no one can hear. Yusei was your lover in his spare time, well you two don't have a strong relationship, but even so Yusei is afraid of losing you

he looks at you unsure and nervous “Tell me!” He says trying to put on a tough guy stance but you can see how he's looking like a paranoid girlfriend, He didn't like seeing that boy laughing with you.. what if the boy is better than him?!

He really is a difficult boyfriend to deal with.
