I just wanted you to know that, baby, you're the best

Public display of affection?

Contrary to popular belief, when it came down to it, Hashirama was the one who most pushed to respect PDA. If things were left to Madara he would just shrug one shoulder, in that unbothered and unconcerned and assholery way of his, and then proceed to molest Hashirama mindless of where they were.

Hashirama had early on in their relationship set very firm boundaries – with heavy repercussion if Madara so much as thought about pushing them. Even before completing his transition, Hashirama had been very strict about kissing in public, bordering on vetoing it.

Even so, Hashirama was always the first one to lean in and softly kiss Madara on the corner of his mouth every time they met outside. Usually, Madara pecked him right back on the cheek before mumbling grumpily. Hashirama still crackled with fond laugh every time.
