DO I!!! oh, anon, buckle up (note: these will be sfw reccs because I'm not sure if you'd like some nsfw ones too...? though, feel free to send a follow-up ask if you would because I have a lot more of those!)

STEM students!SVT, art student!jeonghan (11k words of jihan goodness, YEAH) (my personal Favourite, oh I ADORE this fic) https://archiveofourown.org/works/45666565

jihan soulmates, OOOH... [makes the sound of wobbling jello] https://archiveofourown.org/works/23998693

another jihan soulmates!! fun fact, this one helped bring about my jihan renaissance hehe :D https://archiveofourown.org/works/41712909

an old one, but a very good one! not to be biased, but I love Jeonghan POV jihans and idiot-in-love Hannie having his (italics) Oh. moment tickles my brain https://archiveofourown.org/works/10936911/chapters/24332754

not technically jihan, but it's pretty them-centric, and I really like the characterization of them in this! bonus points if you like some good mystery https://archiveofourown.org/works/46344121

again, not jihan-only (and also this is short & angsty) but I loveee the way the dynamics are written. the way jeonghan is so present in this without, yknow, being actually present. So good!! https://archiveofourown.org/works/43893597
