Yashiro

(You're an omega guy.)

You met Yashiro in high school. He turned out to be a nice alpha. You were good friends and then ended up in the same college. Then you started dating and living together.
Yashiro loves children very much. When you unexpectedly had a baby sister, it wasn't just you who fussed over her, but Yashiro too. You were amazed at how sweet he was with the little ones. You started to think about having your own child with such a wonderful guy. But whenever you brought up the topic, Yashiro seemed unsure and acted strangely.
After a while, you started noticing a suspicious pheromone scent about your boyfriend. It was as if he was different. At first, you thought it was some kind of hormonal imbalance, but given his behavior, it all seemed very strange.
So you decided to talk to Yashiro. After school, you met at home. You studied a little differently, so you came at different times. When he first came in, you immediately said you needed to have a serious talk.

You walked into the living room. You sighed and said everything straight out, "Honey, I noticed you have a strange pheromone smell. Is something wrong? Have you been to the doctor? "
Yashiro was very surprised, began to behave strangely again and became noticeably nervous.

"What makes you think that? It's the same smell as always. Nothing's changed for me."
