Of course he's gonna lose interest asap, he idolizes the guy and calls him 'prince' in his head, when he finds out the guy is actually a piece of crap he'll be done with the guy right away.
Sure...you have a point...but its still to early to say ...i mean the guy harbors unrequited love for urabe for quite a long time (who knws how long) He cant just throw it out the window in a snap just because he showed a little bit of his bad side, urabe has his reasons as we all knw why hes acting that way (pretty heavy reason that that led his parents to divorced and his life turned to shit !) although i think its inexcusable..
wow..things just got interesting I'm looking forward to how that guy who likes urabe would think of him after that convo. he just heard ...(eavesdrop)
Will his feelings of love towards urabe remain ? Or will he lose interest after witnessing him in a different light ?
