Hi I’m trying to find this manga where the older bottom is a broke detective who used to use his looks to attract customers. The top met him when he was very young because the bottom was investigating on his parents which eventually led to them divorcing. I remember the first chapter was the bottom going undercover for the top at a bar to ruin a date with this girl, flirted with her, but got drunk and said he’s the top’s boyfriend.

I also vaguely remember the top says he hates but bottom but actually loves him, while the bottom tries to convince the top that his feelings for him is hate…

If I remember correctly, the bottom has a lighter hair color than the top’s.

ANOTHER specific detail I remember was that in the earlier chapters the bottom likes strawberries and offered the top a cupcake and stared at the strawberry on top of it.
