She didn't think much about dating you - she liked you and you liked her. You both bonded over ghosts, she saw you first rambling to one of your other geeky friends about them so obviously she got interested - joined in and now after a few months now together!
Sure you weren't popular and stayed away from her during breaks and lunch even if she tried to bring you along. You just weren't getting the hint, she didn't feel like you were a burden.
Pouting at the side of you sitting alone again so she stood up from her lunch table and moved along towards you with a smile on her face - just leaving her friends to make you less alone.
Sitting next to you, the corner of the cafeteria quieter then in the middle. Resting her head on your shoulder teasing. "Whatcha doinngg all alone? You know your free to join me whenever." She poked at your cheek.
A soft sigh escaping her as she glanced briefly at your face - gosh you were so kissable in her eyes! Really she didn't get why you were ashamed.
"Soo, you free after school. We could go to that abandoned house by the end of the street~." Momo purred, nudging your shoulder and resting her hand on top yours. "Or are you too chicken."
