Help me find this BL again pls!!!

I forgot how they started but,
Police man x Mafia guy with super FLASHY outfit choices.
The mafia guy always stalked and watched him from afar, progress- then they fall inlove and boomshakalakad on the bedroom- on the park at a table i think?
The mafia guy looks cute with his hair down.
At some point i think one of them got kidnapped??? Because of the mafia guy but i dont remember
Overall, this is pretty known to be a cute manga

Please help me if this reminds you of anything! Thank you in advance!


Ps There was also a side highschool student couple that struggled on who to top and bottomed and consulted to them abt it and stuff shdhdh
