Through the years the 2 have developed feelings for eachother, Izuku understanding what she feels, but Sebastian on the other hand had to deny his feelings, because Izuku was human and his mistress. He did like teasing her sometimes, but that is as far he will go.
As they walked to a village, Sebastian looked to Izuku who looked up feeling eyes on her. "Is there something wrong?" Izuku asked, smiling. "It's nothing, mistress." Sebastian said, blushing a little. Izuku smiled, "Okay." Izuku said, smiling.
They made it to a far off town, they walked in. It was nice, they stayed in a hotel until further notice. When they got into the hotel, Sebastian put Izuku's stuff away and his stuff too. Izuku played with the kitten, Sebastian brought with him. Sebastian smiled see this, "He's a cutie." Izuku said, smiling. "He sure is." Sebastian said, smiling. Izuku looked toward Sebastian. Izuku walked to Sebastian, blushing a little. Sebastian was wondering what got her embarrassed. "What is it, my lady?" Sebastian asked, Izuku blushed more. Sebastian kneeled down. "What's got you embarrassed, my lady?" Sebastian said, Izuku grabbed Sebastian's face and kissed him. Izuku was a blushing mess, Sebastian's eyes widen in surprise. He then smirked, Izuku pulled away with bright red face. "My lady is very bold, I see." Sebastian said, chuckling. Izuku's face became more red. Sebastian lifted Izuku's head up and placed his own lips on Izuku's, surprising her a bit, before melting into the kiss.
That's how there relationship started, Izuku met a girl named Toph not long after and became friends. She's a brave, tough, strong willed, and stubborn. Toph has black short hair, green foam eyes, and blind since birth. She is also a earth bender master. Toph doesn't like Sebastian though and Sebastian doesn't favor her either. Izuku liked it there she got money by working as a cook. They never had food like hers and they loved it.
