The amount of feelings he could see Hayato show after this exchange of confessions was amazing. Ryuutaro thought that their mutual love had been pretty clear after all the time they spent together, but he also found out that having it spoken out loud still made a difference. Though that difference seemed to affect Hayato so much more than him.
And with those 'thank you's Ryuutaro realized just how much power he'd held about his boyfriend just a moment ago. And still did.
And he found out that he liked it. Not because of any dubious reasons, but because there was something of Hayato that he could protect.

The deep and meaningful train of thoughts got interrupted and lost in the further touches a moment later. Ryuutaro kissed Hayato back, finding out that now he was actually feeling way more confident about all of this.
One of his hands was placed around Hayato's neck as the other started wandering up and down his boyfriends exposed torso.
