So basically:
-Both of them have realized their love for the other.
-They had also gave up on their original lover goal. (MC and black hair girl, FMC and blonde boy)
Which are good, those are good things.
The damn problem is that neither of them have a clear idea of what the situation is.
-MC knows FMC gave up on the blonde guy cause a friend told him, but I'm pretty sure FMC hasn't directly confirmed that to MC yet.
-This chapter shown that FMC hasn't known about MC giving up on the black hair girl.
-Both of them HAVE TO have a slight idea of the other loving them at this point, it's impossible not to, but then again, neither of them can't be sure because:
+)FMC, being a tsundere trope, can never give out a clear answer, sometimes outright rejecting of she liking him when she talks to him about her feelings. That, plus MC having an inferiority complex (IC), mean that we're getting fucking nowhere from MC's side.
+)MC, having IC, will keep trying to psych himself out, always thinks FMC's actions are due to nature or have a deeper intention, or that he's not worthy of her.
Unless:
A: The author finally draws for MC a pair of massive balls so that he can just go #YOLO and try to confirm FMC's feelings.
Or
B: FMC can't wait anymore, maybe out of fear of falling into the same situation of the black hair girl, so she goes and confirms her feelings to MC.
Unless those or something similiar to those happened, we ain't seeing the end anytime soon.
Ps: There is also the chance of both of them go and confirm their feeling but that chance is so slim that we might as well not consider it an option.
