The translation is trash MTL

The guy said he loves someone else and will never confess to the girl, all of this with the girl near him.
Never told the girl it was a lie, never tried to clear the misunderstanding
The girl acknowledged the situation, moved on and started going out with other guys, got a boyfriend, and now the guy regrets and is dying inside???

This is basically yeenagers being fucking stupid, male childhood friend got awkward and flustered, said what he said as a lie but never cleared up that it was a lie to he girl. Though she avoided him at school the next day and afterwards it's weird that he never just went to her house to talk to her and let this go on for a month.

Same premise as "Take everything from you" from Takotokite.

I guess this is a good lesson from a hentai, always clear up misunderstandings, or else face the consequences like the guy in this story

That is a good lesson to be learned for sure, about the misunderstandings.
The other lesson is that a girl who falls in love with a piece of shit is either stupid or a piece of shit herself.
So the MC is twice the idiot: once for speaking shit because "boohoo sho embarrashed" and twice for staying near her and the asshole.
