Oh... I didn't see that - I thought it more like she misunderstood him liking Haruka (whereas he actually likes her...)I think it's hinted that she's already caught onto Haruka's feelings for him and that's why she looks disappointed when he says that he wants to help both of them because she thinks Haruka's gonna steal him away from her.
It’s subtle and usually when he’s with his friends (like when he’s having friendly banters with Itsuka). He is more natural with Akiha/Haruka.One thing I dont get - where he is playing a character? Author really didn't show us him in daily life, all we've got - seeing him always with girls, acting as always, it like no build up, just his words, and that's bugs me all the time...
Hope next chapter will clear the air around this issue
