AFTER their talk, Astrid noticed that Reas became visibly more relaxed. As if a burden on his shoulders had been lifted. Well, that's probably only natural, since he seemed to be having trouble analyzing his own feelings. He must be at his wit's end if he even resorted to asking Astrid for advice, knowing that there's a high chance that he would just tease him.
But since he's a good brother, he would wait after a few more days passed before teasing him about what happened today. Astrid sipped his tea and smiled inwardly at the thought of teasing his brother.
Anyway, it really came off as a surprise to him that Reas would actually ask him for advice. He thought it would take years before his brother's love cells fully bloomed. He didn't expect that after just a few months, Reas would change from an indifferent teenager whose only interest was Mechas to someone who would wonder about what he felt from a person.
