After Momo had ran out of the restroom, Izuku changed to his physical form to chase after her since he can't leave his bound place in his spirit state.
"Hey kid, wait up." called out Izuku, grabbing Momo's arm to stop her in her tracks.
"Leave me alone!" yelled Momo, shrugging off her arm from being held by Izuku's ice cold hand.
"What's wrong with you? Why did you just suddenly made an outburst like that?" asked Izuku.
"Why didn't you tell me?!" replied Momo, with tears still trickling her cheeks.
"About what?"
"That you will just disappear once you granted my wish!" answered Momo in a loud manner.
Izuku was quite taken aback by this response. Izuku thought that once Momo gets her wish, she and Shoto would be happy together while he would just perish completely without a trace. It never once slipped his mind that Momo would care if he would disappear since by then, she would have already got her wish granted.
"But, I thought you won't want to concern yourself with things like this." stated Izuku.
"Of course it's my concern! I don't want you to disappear okay?!" cried Momo, gripping Izuku's shirt tightly.
"Why?" asked Izuku, confused. Ever since he became a ghost, Izuku's emotions had also descended rock bottom making him insensitive to this.
"I don't know myself! When I heard you say that you would just go after you fulfilled my wish, my chest suddenly hurt and I don't know what I'm feeling."
"...If you don't want me to go, that means your wish will also not be given to you. Do you want that?" pointed out Izuku gently holding Momo's hands.
Momo didn't even have a speck of hesitation when she opened up her mouth and answered Izuku.
"I don't care if my wish won't come true! Just don't leave me!" replied Momo, hugging Izuku tightly.
"Look Momo, I have already been in this world for far too long already that I lost count of how badly I wanted to escape this." explained Izuku with Momo still hugging him.
"Since I am doing my best to grant your wish, won't you be a good girl and grant me my only wish too?" asked Izuku, giving Momo a warm smile from his cold lips.
After hearing Izuku's plead, Momo didn't get to say anything as she just kept hugging Izuku with tears still flowing from her onyx eyes.
"How about this, while I'm still here won't you accompany me to explore this world before I leave?" suggested Izuku.
Momo's eyes widened as she heard it.
"...Hmm." nodded Momo still embracing Izuku's cold body.
"After my classes ends, wait for me here. We'll go to a bunch of places you have never experienced before. I'll make you love this place to the point you will never want to leave this place." said Momo, wiping off the tears in her eyes.
"Alright." replied Izuku smiling.
Just as the two had talked about, Momo came directly towards the old school building after class to take Izuku to roam around the place.
"Let's go Izuku-kun." said Momo as Izuku warped back to his physical form.
"Where shall we go first?" asked Izuku as he held Momo's hand.
Just after Izuku held her hand, the both of them got transported outside the school campus which got Momo surprised.
"What happened?!"
"Don't worry. I teleported us out to make things easier." assured Izuku.
This gained a sigh of relief from Momo. She then gently gripped Izuku's hand as she lead the way to their destination.
"Let's go have some fun!" exclaimed Momo, excitedly.
The first place they went to was of course the mall. It has everything they could go to.
"Can you eat in your physical form Izuku?" asked Momo to make sure.
"Yeah I can"
'Although I can't taste anything.'
Even though Izuku can literally can't taste anything, he don't need to tell this to Momo since she seems to be enjoying herself so all is good.
"Perfect!" replied Momo.
Momo pulled Izuku inside a fast food chain.
The both of them then ate various kinds of food which are fried chicken, fries, burgers, ice creams and several other things. Although Izuku can't feel like he's eating at all, he just kept a smile on his face pretending to enjoy the food.
After they ate, Momo again pulled Izuku and this time it's the arcade.
"Let's play next. Surely you haven't gone in this kind of place before." suggested Momo.
"No, but it seems fun." replied Izuku.
The two of them then played inside the arcade.
She is now having much more fun being with Izuku more than she is with Shoto and Momo is yet to notice this.
