In that regard the ending unintentionally sums up the entire story.
A god tier (might I say chad) MC pushes through the obstacles around him to get what he wants, both girls fall for him but WAIT, need some drama so have one girl disappear and come back three years later making the whole arc pointless. Its extremely unfortunate that the love life wasn't explored at all. The arc, like many others, shows a general lack of direction this manga chronically suffered from. I actually find page 13 to be the true ending, both girls overjoyed and in the arms of MC. Despite this, it was refreshing seeing a very decisive MC that most romcom's lack.
7/10, would weakly recommend a reading, you can't really go wrong. If an english paperback of this is released, I'd likely buy it.
