beryl? kael? is the author a league of legends player?

 

[martianpaws]

while the romcom setting is nothing too special

The art and everything is well executed

 

[Foreus]

it's weird but still kinda cute

 

[WhiteRabbitBR]

It would be funny if the older siblings are doing the same

 

[ZzombieNoel]

So, I'll try to make predictions
Interests:
MC -> FMC (Pretend FMC's sister)
FMC -> MC (Pretend MC's brother)
Both are doing the same thing
MC's brother -> FMC's sister (pretend FMC)
FMC's sister -> MC's brother (pretend MC)
They're doing the exact same thing in their point of view

But hey, I just made a theory, now time to actually read
