Somebody please tell Yashiro that yes, it happened, he really did fell in love again after all these years.
His past conversation with Kageyama asking him how it is to sleep with only one person ( meaning how does it feel to be in a committed relationship)
His past conversation with Doumeki asking him how does it feel to fall in love with someone ( his analogy that for him it was painful like reaping a bandage on an open wound)
His current conversation with Kageyama asking him why he chose Kuga and not him ( meaning how do you know you love X and not Z, how do you know someone is the one? )
All these are poking around are about the same question Yashiro is trying to answer: Is this new feeling really love? Did really happened to me at this point of his life? And can I really be in normal relationship with someone?
Yashiro's love for Kageyama is not much of reference, he was young when he fell in love for the first time and it was barren, never tested beyond fantasy, never tested , or tested for routine of life together, never tested with intimacy nor fidelity. Mostly never tested before against a new stronger love.
So he is going around asking these questions to the people he knows have fallen in love in normal way... Doumeki, Kageyama. Truly he is just as inexperienced as a teenager falling in love once again and this time it involves someone loving him back so it's new and he is still dumbfounded that he got himself in this situation.
