I've read all of the ones listed except for The Three Times and Ties of Compassion. I'd pick The Three Times since it's about uni, I'm in uni so I kinda want to read stories about uni stuff, the one I read recently left me down, was expecting something more serious — it's All Blue — the manga has a nice ending, an interesting one and in general a nice criticism of harmful stereotypes, some moments had their place, like, were meaningful to an extent, some jokes were funny, some others were not since it's degeneracy level jokes (tho it makes part of the general criticism, tho they still overdo harping on some weird issues imo) and it's more like not what I wanted, something that can have humor but that would be more centered in uni students struggles, mentalities, feelings irl that carry on to uni time, etc...
