Damn, so he still took the crappy advice from his friend. Hiromichi is the guy with a GF... he should be dispensing advice, not taking it from these single dudes who for all he knows is just spewing BS.
Really bad call to hide it, it'll just hurt Haruka more the longer it stays a secret. This time bomb started ticking the moment Shigure decided not to tell her sister. It's just asking for a scenario where Haruka sees them both going to his house.
My gripe was over hiding the stepsibling status from the GF. I don't see any good reason why being stepsiblings has to be kept a secret from her.bruh what did you expect? the title literally says i kissed my girlfriend's little sister. 🗿
I second this. But still, thanks for the scanlation GD Scann!Um.. Translator-san, can you change word "big-bro" to "onii-chan"? I think It would be comfortable and cute to read rather than using "big-bro".
