Training was important but you came first for Iguro. As soon as a letter from you came he dropped his training katana and opened the letter in a flash, quickly reading the contents

'Mr Iguro, how are you? After training today, i had tea with Tanjiro! That Tanjiro..when he eats or drinks something sweet, he looks like he died and went to heaven! He's so adorable!'

His grip on the letter tightened and his jealousy was visible in a purple aura surrounding him

"Kamado!" He mutters in rage
