Off the clock

the human parts

Family

Girl dad

Kiara keeps me humble and inspired. She has her own little corner at kiaraasteria.me.

Playing

Slow games

Farming in Story of Seasons and over-managing a virtual football squad after Kiara's asleep.

Listening

JKT48 & K-pop

Oshi lists, comeback seasons, and the occasional concert-light-in-the-living-room evening.

Faith

Grounding

The thread through all of it. “inna ma'al usri yusra.” With hardship, ease.
