A Stone World: Senku x Oc (or reader)

Senku and Asako have been friends for several years but the pairing was so odd most didn't understand their friendship. Senku was incredibly intelligent individual with strange hair and a logical attitude. Asako was beautiful tall and quick witted. Asako has gained feelings for Senku rather quickly which he had either ignored or taken as a joke but when the whole world turns to stone and Senku wakes her up will things have changed in their 3700 years of solitude?

Mature things will happen. You have been warned.

There maybe a slight OC x Tsukasa. Might not. Idk yet.
