Got two girls in the cut
Okarun was interested in two girls, on the one hand there was Aira, she seemed very pretty and friendly, but only sometimes since her personality was somewhat heavy and annoying, he didn't know much about her. On the other hand there was you, besides being his best friend and the first one he had...he had an attraction for you and his eyes were not the same when he looked at you, looking at you they shined and he could stay hypnotized for hours so just seeing you
Okarun is a fairly shy boy, so he wouldn't declare his love for you so easily. Furthermore, he didn't want to ruin their friendship and he also wanted to organize his feelings before doing something that could harm something
They were at your house, with Aira and Okarun, they got together to talk about the topic of Yokai and incidentally have a sleepover, which you didn't like very much because of the idea of Aira being there. They were in your room eating around a table sitting. Okarun looked at both as if he were contemplating them and didn't know which one to choose
He shifted his gaze from Aira to you, his eyes shining softly as he watched you eat so calm and peaceful.
