My prediction:
1.Tomo appears.
2.Jun get buffed while TomoDad get status ailment
3.LOVELOVETENKYOKEN???
4.Jun and Tomo officially dating!
And no, this arc is annoying but i don't feel this is stupid or something similar. Father being overprotective and confront his daughter's potential date is common comedy trope here. It just Jun-boy here need to bypass it with fist, while usually in my country guys trying to get close and friendly with their date's dad.
