10-Nen Buri ni Saikai shita Kusogaki wa Seijun Bishoujo JK ni Seichou shiteita - Ch. 1 - After 10 years.

[Eighty-six]

This is the second time I've seen a "grew up with three girls as an older-brother-like figure, went away, came back in 10 years to find them aged into 17-year olds still pining for me and still retaining some of their past personalities" (third time, if we don't account for the age gap feature), which is odd.

...can I get some of this but with the sexes reversed?

Oh an age gap manga huh?

So basically nothing will happen until the end when they timeskip to graduation.

She's 17, so there may be some shenanigans she starts up by herself (can women in Japan still get married by 16? that was a premise-point in Takane and Hana).

Maybe the guy's a vampire or some youkai, in which case none of this matters because you're not checking mystical creatures who can bisect you with a thought.

I don't think she really has an attitude, but honest if this turn into an harem I'd be okay with it,since all three of them looked breedable

excited to see how the tanned one turned out, I hope she's still a tomboy

100 days of vacation per year?!?!?! Where the heck do I sign up?!?!

Wait, hold on a second, does this account for Saturdays and Sundays? Are they considered within those 100 days of vacation or are they included as time-off separately?

So this is "First Love, Again and Again," but sans the chad protagonist and with an indisputable winning heroine? Oh well, let's see how it goes.
