I don't think so. Yashiro has long thought of himself like a dirty rag that should be treated roughly. Maybe he wouldn't have any idea someone can care about him.
And yet he knew that the yakuza 20 years ago had feeling for him so... However I also think that he's not aware of Ryuuzaki's infatuation, he probably thinks he's a pretty funny guy and the sex feels good, end of. I think Yahsiro would probably not "play" with someone's feelings unless he felt threatened, hence why he tricked that guy into getting fired long ago and then also fired the recruit that had fallen in love with him over a stupid mistake he made. It's just that Hirata got me thinking, if Ryuuzaki survives I hope Yahsiro somehow notices/acknowledges his feelings, although it wouldn't really change anything.
I hope so,too since Ryuuzaki is one of my favorite characters.
About the yakuza 20 years ago, his way of sex with Yashiro was obviously affectionate,( unfortunately he was simply not Y's kind of guy though..) that made Y notice his feelings,I guess.
From the start Y basically thinking` becoming a yakuza is not good' may be one of the reasons why Y set him up and said `good for him,he is not cut out for yakuza' after the yakuza was kicked out.
Rereading this manga, R×Y’ｓ sex has been gang-rape-style or rather sadistic,and R is usually not honest type at all, that's why I thought Y wouldn't notice his infatuation.
Do you think this is as Hirata said, that Yashiro is aware of Ryuuzaki's feelings for him ?
