"What? They're dating? Is that a rumor?" NotWearingPants asked curiously. From his expression, it was his first time hearing that. He knew that Arthur was avoiding Sylvanas and thought that Arthur didn't want Sylvanas to get too close. Arthur had never liked Sylvanas. Instead, Arthur had a better impression of Raintea.
Arthur wouldn't take the initiative to develop his love life. To prevent awkwardness as friends, Arthur avoided Sylvanas as a subtle hint. That was what NotWearingPants thought. When he heard the rumor from Peasant, he became anxious. Did Arthur avoid Sylvanas so that Raintea wouldn't misunderstand?
If that were the case, it would be a big problem. Sylvanas might not be able to accept the truth.
