MTL - Poison Genius Consort 2: Emperor’s Swallow - Chapter 961 You can't come back

One day, two forum posts titled “I Seem Unsuited for Dating” appeared on Promontory Forum’s Feelings board nearly at the same time.

User A: 「I have a severe case of mysophobia and possessiveness. I cannot accept it if my girlfriend has had relationship experience. I went to see a psychiatrist, but I haven’t improved. I might truly be unsuited for dating.」

User B: 「I think I might be unsuited for dating. I very much enjoy the ambiguous phase of sounding out each other’s feelings, but after becoming official, if they want to hug me, or perhaps kiss me, I will immediately feel nauseous.」

Internet User: 「I beseech that the two of you be together. Don’t go and harm anyone else.」

2: Don’t always try to save the world, it will be bad luck to be a Virgin in other planes.

3: Don’t let go of good things, maybe you will lose a great opportunity because of this.
