What a cute 'friendship'? dynamic lol
I get the concept of bar hopping but other than some places closing it'd prolly be best to stick to one place unless drinking in japan is dirt cheap too
And of course she has a shitty ex. Seems like a yuri backstory that's common too tho as far as i know this isn't gonna have any more romance, straight ships or no, not that it needs one
Makes me wonder what Tsundere's bf/husband/partner is like , unless she only acts that way towards this mc
