Hot spring bath ~An unexpected exclusive contract with the hot spring fairy~

Iroha hasn't come back since she went to the hot springs. A bad feeling crept in, so I went to look for her, and sure enough, she was still in the bath. And as soon as she saw my face, she gave me a big smile and said, "Genba! Welcome to the land of fairies!" ...This is a hot spring, isn't it? It seems her previous declaration of "becoming a hot spring fairy" is still valid. Even when I told her to go home, she kept giving reasons: it felt good, she's a fairy, and so on. Honestly, what a pain. But, once I got in next to her, I understood her feelings a little. The moon hung in the night sky, and in the distance, I could see a fantastical palace and waterfall. Cherry blossom petals floated on the surface of the water, and the lantern light flickered gently. ...It's certainly a view you could gaze at forever. Even so, I can't stay. Just as I was thinking that, Iroha grabbed my sleeve. "Genba, won't you stay with us a little longer?" ...That look on her face is unfair. In the end, I decided to stay a little longer. After enjoying the hot springs together for a while, I suggested we go home again. But Iroha said "just a little longer" again. Then, a thought suddenly occurred to me. If she doesn't come back, I'll be lonely. ...What if I just told her that? "If you're a fairy, then come back to me." Iroha's eyes widened. "Because...I'll be lonely without you, Iroha." After saying it, I felt a little embarrassed myself. But the effect was greater than I expected. Iroha's face turned bright red, and while calling me unfair, she finally decided to go home. ...Hehe. Sometimes, it's not so bad to be honest with her feelings. That thought lasted only a moment. "Then, from now on, I'll be Genba's personal hot spring fairy!" ...Personal? "We'll take a bath together every day!" Wait. How did it come to that? Even though I said I was troubled, Iroha just smiled happily. In the end, even after changing into her yukata, she clung tightly to my arm and wouldn't let go. ...Well, I guess it's okay. As long as Iroha comes back, that's enough. Besides, I've never disliked the time she's by my side. However, there's one thing I want to correct. **I went to welcome the hot spring fairy, not to sign an exclusive contract.** ...Does Iroha understand that?
