A visit one day:
Lu He: What's this?
Heze: I found it on the road while weeding the little orchard behind the mountain.
Lu He: ...Didn't your mom tell you not to bring random things home?
Heze: Then what should I do?
Lu He: As upright, exemplary young people of Konoha in this new era, we should return found property to its owner for the sake of social stability and national prosperity.
Heze: Who's the owner?
Lu He: Looks like we can only return it to where it belongs. Take it back to where you found it and toss it there. We mustn't encourage bad social habits like faking an accident for compensation.
Heze: Yoshi!
Sasuke, who had fainted from training fatigue and was just waking up: ...

Lu He: So a man marrying into the family has to make it through one challenge after another. He has to conquer the world and win over his wife-obsessed brother-in-law and father-in-law. Do you have what it takes?!
Sasuke: Too much trouble. Forget it.
Lu He: ...Where's all that promised passionate romance?
Sasuke turns and walks away.
Lu He: Chotto matte! Young master! I can carry this whole melodrama by myself! All you have to do is sign the marriage certificate!
Sasuke: ...I honestly think your chuunibyou is worse than mine.

The female lead will probably look like this↓↓↓↓
And the much-anticipated second young master:
