I want Yuiji to be the one to like him first because I feel like throughout the manga Yuiji says stuff that indicate him possibly falling for him. I personally feel like Yamato isn't quite there yet but I just think it'd be interesting if Yuiji ends up realising his feelings first if he does fall for Yamato.
Yes I think that too, Yuji liked his ex girlfriend, but I think he didn't love her (I don't mean in bad way). But I think Yuji first start thinking about his feeling and his act, when he meet Yamato, and saw his love for his friend. It's like before Yujii was like careless, but after know Yamato, he start to think deeper about things and feeling, like he start to want to know about what he really want.
sorry I don't know how to descrip correct, but I hope you know what I mean.
yes it seems Yamato start has feeling for Yuji, and that's be great. I hope Yamato don't suffer anymore from one side love.
sorry for long comment.
I definitely agree with you about Yuiji not actually being in love with his girlfriend. I wonder if he does fall for Yamato that he'll realise he never had feelings for Mao (is that her name...?) He puts way more effort into Yamato than he did for her.
Definitely. I honestly hope the author doesn't finish the manga in the next volume because I would love for Yuiji and Yamato to end up together. I totally get why though if she doesn't make them a couple because they have a beautiful friendship. However if she plans on making them a couple doing it one volume and apparently one volume is 8 chapters would be rushing their romance and ruining it TBH. I rather it be done properly and not rushed in a small amount of time.

Do these events somehow foreshadow that Yamato might start to love Yuiji romantically??
Actually, there are a lot of events which seem to hint that romantic love will happen between them (whih I hope so so so much! ><)
Btw, what could be the role of Hibino, the teammate kouhai, in the next chapters? Hmm
