therapy game 100%. The first one is so uncomfortable to read.

Which one you should read or which one do I like better? Both are my favorites and when I bought physical copies, I was so happy. But I do like Therapy Game better cause I love Minato and the relationship dynamic. I do recommend both stories often. Therapy Game and it’s prequels are 1-4 on my manga list and then Jackass is #6.
If you want to read, I would do Jackass first because it’s short. It’s only one volume and it reads great. There’s an openly gay character who is sassy but gives pretty sound advice. I love the main couple too and the art is fucking top tier. Scarlet Beriko is amazing.
Therapy Game is a spin off of XXX Allergy and Secret XXX. I highly recommend reading those before Therapy Game because Minato is introduced in Secret and you understand his brother complex a bit. You also understand how Minato and Shizuma met. My theory is that Meguru Hinohara wrote Minato, loved him so much and wrote Therapy Game so he could have Shizuma. Shizuma is so good for Minato, but Minato is the one who steals the show for me.

Therapy game, but therapy game is actually a spin off so you can read in the order xxx allergy-> secret xxx-> therapy game-> therapy game restart if you want to understand fully, because the first couple appears a few times in the therapy game too

jackass is like my favorite BL ever lol. therapy game is good too but i never got the hype
