Awwwww...I just woke up and got assaulted by this cute scene! Nino got annoyed but for sure he's just ''plainly annoyed'' and nothing more than that because he knows Satoshi. He's also worried.
Cute Jun messing around and hugging his teddy bear is sooooooo cute! I caaaaaaaaaan't! (∩´﹏`∩) He just loves watching how Satoshi paints and tries to imitate him (insert Juntoshi LOL). I can imagine Masaki making things dirty, a terrified Satoshi comes in and Masaki just smiles brightly with a cute ''oops!'' and wide sheepish grin. Well, if you think about Nino's bratty side, he will forgive Satoshi for screwing things up because he knows he can do all the naughty things to him as his revenge. Hahahh thank you dear!
