Three days had passed since Noa started struggling to create a new, innovative code, and he finally managed to complete it. This code alternative would be a big step for their mission.
So-Rin really helped Noa during these three intense days, especially in terms of calming her mind which was almost burnt out due to work pressure. Whenever Noa felt frustrated or in doubt, So-Rin was always there by her side, providing moral support and practical help.
So-Rin also often brought Noa's favorite snacks and reminded him to take a short break.
Apart from that, So-Rin was a good listener. She was always ready to listen to Noa when Noa needed to talk about all the frustration and uncertainty he felt. So-Rin's understanding words and constant presence made Noa feel that he was not alone in his struggles.
