So till the chapter 6, my impression is,
1. The MC thinks the FMC kinda hates him, but kinda doesn't – let's just say neutral vibes.
2. The FMC suspects the MC still kinda has feelings for his childhood friend.
3. The childhood friend ships the MC and FMC, creating moments for them but also occasionally messing things up.
4. The wingman guy thinks the childhood friend likes the MC and knows the MC likes the FMC, but he's rooting for both of them.
I think the story's gonna be full of misunderstandings, but I hope it'll be like Gamers anime, funny and don't cause any problems on the progress.
