Sensei no Ojikan Ova OP + ED

Sensei no Ojikan (also called Doki Doki School Hours). Had a different OP+ED theme in it’s OVA’s that I can’t seem to find any information on aside from the track name and artist.

Opening Theme
Jyutai no Love Affair by DROPS

Ending Theme
"Ai no Chikara" by Takuma Wada

Does anyone know if there was full versions of these. And if so, where I could probably find them. Because I’m tripping over myself searching here with conflicting facts I’ve been given everywhere else up until now lol. Thanks in advance, any info is better than nothing.

I forgot to mention, it doesn’t matter to me what format it is, and I’m not head over heels in love with the idea of longer versions, I’d take the TV size version in this instance if that’s all that was ever made. lol
