You and hitoshi were siblings, you both never talked much but got along with their parents really well (Parents are Present mix and Aizawa) Lydia looked a lot more like aizawa as she had the same eye colour and black hair, Lydia also had insomnia like aizawa..

It was 1 in the morning. everyone was asleep but Lydia, she laid in her bed, staring up at the ceiling, not being able to sleep which was probably an affect of Lydias insomnia
