My favourite thing will always be Kaveh seeing how big Alhaitham has gotten and either getting PISSED that he got outgrown. OR all sad because NOOOOO MY SWEET LITTLE JUNIOR IS ALL GROWN UPPPP I CANT BABY YOU ANYMOOOORE
The latter usually being when Kaveh is drunk and he’s getting nostalgic he’ll start whining because Alhaitham was so cute as a kid and he always wanted to protect him as his senior then Alhaitham had to grow up and become all tough and strong and big WAHHH WHERE’S MY LITTLE BABY JUNIOOOOR

Every time Kaveh talks about it Alhaitham has his usual stone-face on but internally he sometimes finds it cute how flustered Kaveh gets over it. Other times when Kaveh seems genuinely upset there’s a part of him that almost feels guilty about Growing Tall like…. Damn…. :( why’s he so sad…. Sometimes you can tell he feels bad about seeing Kaveh so upset bc he’ll slouch slightly more just to be a bit shorter next to Kaveh (sometimes he ducks down to be even lower and Kaveh starts cooing at him drunkenly)
