You should try this if you want two girls instead

an adventure with implied wlw is highly unlikely. Even adventure with a woman MC is rare.
This one has some implied wow between the sister of "MC" and the MC but it's a straight romance as far as I know.
How to Get on the Main Character’s Flower Path
and this one is better on webtoon but also (a little) implied wlw
Hand Jumper
the witches' isle might be something similar (although wlw(?))
here are some implied (action) manhwa with bromance I found quite good.
The Fundamental Law
Regressor instructional manual (the novel has better bromance as I've heard but it's still good)
An Insincere Idol’s Blank Slate
The Evil Ring
The S-class that I raised
Myther
Book of the dead
Obsessed Butler (more a comedy but the guy is often shown in a "sexy"/romantic way and MC is a literal cat)
Too lazy to find more. have fun and I hope at least one might be what you're looking for ( ◜‿◝ )♡
Maybe check those if you don't know them already:

Does anyone have any action stories with bromance? Like ORV, TSCTIR, Lout of count, stories like that with heavily very very very heavily implied bromance but not actual romance? I'm so FUCKING sick of romance bc with straight action boys and girls can't just be friends apparently so the relationship is never just implied and im tired of seeing stories with more than implied relationships. Preferably don't want aura farming slop written by a man and preferablyyyyy no fan service. YOU KNOW WHAT WLD BE EVEN BETTER I WANT THIS BUT WITH TWO GIRLS AND ABSOLUTELY NO FAN SERVICE PLEASE OH MY GOD AUGHHHHHHH idc as long as it aint no straights
