"Mrs.  Banerjee , did  you add new students for the enrichment group yet?"

"Ah~ Tae, why don't you collect it rn. New students please write your contacts on a piece of paper."

Thats how Jimin has to give his number to Taehyung, he even added a little star and cute heart on the paper and gave it to Taehyung, who leaned a bit and pressed the piece of paper near his heart and smiled in victory. Jimin's heart melted at that.
